Set the key to true to attach the .aspx extension in postback URLs.

<add key="CMSUseExtensionOnPostback" value="false"/>

false

CMSUseTrailingSlashOnlyForExtensionLess

If the Use URLs with trailing slash setting is enabled in Settings -> URLs and SEO, this key determines whether the system adds a trailing slash only for URLs without an extension.

For example, enabling the key ensures that URLs such as /googlesitemap.xml do not have a trailing slash.

<add key="CMSUseTrailingSlashOnlyForExtensionLess" value="true"/>

false

The system provides an output filter that automatically resolves all virtual relative URLs (~/<link path>) on the side of the MVC live site (based on the environment where the site is actually running). This filter prevents content editors from creating invalid links in cases where your MVC application does not resolve URLs (by processing the content using the Html.Kentico().ResolveUrls method).

If you wish to disable the output filter and resolve URLs manually in your code, set the key to false.

<add key="CMSMVCResolveRelativeUrls" value="false"/>

true

CMSDisableAdministrationInterface

<add key="CMSWebAnalyticsSlidingIPExpiration" value="false" />

enabled

CMSAuthenticationType

This key overrides the values returned by the IsFormsAuthentication and IsWindowsAuhentication methods in CMS.Helpers.RequestHelper.

You will typically use this if you are using a custom authentication provider whose authentication type is a non-standard one (e.g. Federated authentication) to make Kentico handle it as if it was windows or forms authentication.

The following values are available:

• default: standard behavior
• forms: IsFormsAuthentication always returns true, IsWindowsAuthentication always returns false
• windows: IsFormsAuthentication always returns false, IsWindowsAuthentication always returns true
• both: IsFormsAuthentication always returns true, IsWindowsAuthentication always returns true

<add key="CMSAuthenticationType" value="windows" />

false

CMSPhysicalFilesCacheMinutes

Sets the number of minutes for which clients consider physical files to be valid and up-to-date when using client caching (i.e. the length of the client cache expiration time for files). Specifically, the key determines how the server sets the Expires response header for file requests.

The key only applies to files stored on the file system that are served using the GetResource.ashx handler. Other types of dynamic files use the expiration time set in Settings -> System -> Performance -> Client cache (minutes) within the administration interface. Physical files that are requested directly use the IIS client cache configuration.

See also: Caching files and resources

<add key="CMSPhysicalFilesCacheMinutes" value="60"/>

<add key="CMSEnsureSafeUserNames" value="false" />

true

CMSEnsureSafeRoleNames

Indicates if the system replaces forbidden characters in the code names of roles imported from Active Directory.

If the key is false, you may experience problems with roles names containing certain forbidden characters, for example with leading underscores characters ( _ ). Therefore, it is NOT RECOMMENDED to set the key to false.

<add key="CMSEnsureSafeRoleNames" value="false" />

true

CMSForbiddenUserNameCharactersReplacement

The default value is: ^[a-zA-Z0-9_\-\.@]+$

^[a-zA-Z0-9_\-\.\\@!#$%&'*+/=?^_`{|}~]+$

Note: The key does not apply when processing the names of external users, and does not affect replacement of invalid characters in the names of users imported from Active Directory.

<add key="CMSUserValidationRegEx" value="([A-Za-z0-9-]+)" />

CMSForbiddenURLValues

The characters entered as the value of this key are forbidden in URLs (page aliases and URL paths) and will be replaced automatically by the character specified in the Forbidden characters replacement setting in Settings -> URLs and SEO.

By default, the following characters are forbidden:

\/:*?“<>|&%.’#[]+=„” and the space character.

If you add this key to the web.config, its value will override the default forbidden character set. This way, you can either allow some of the forbidden characters or add new ones.

Please note that it is recommended to keep the default characters forbidden, since they may prevent certain types of URLs from working correctly if entered into URL paths.

Also, keep in mind that some characters need to be escaped in the web.config according to standard XML rules, e.g. use HTML entities instead of HTML reserved characters.

<add key="CMSForbiddenURLValues" value="\/:$?&quot;&lt;&gt;|&amp;%.&apos;#[] =" />

CMSLimitUrlReplacements

While enabled, consecutive forbidden characters in URLs will be replaced by only a single replacement character and forbidden URL characters located at the beginning or end of the path will be removed completely instead of being replaced.

<add key="CMSMediaFileMaxStagingSize" value="1024" />

2147483647 (int.MaxValue)

CMSStagingTreatServerNamesAsInstances

On Kentico instances that contain multiple sites and use staging, changes made to global objects produce staging tasks for all staging servers across all sites. If you synchronize such tasks at different times on different sites, you risk overwriting newer data with the data of old synchronization tasks (we recommend synchronizing such changes at the same time on all servers and sites).

If you have full control over all sites on your instance, you can define the same set of target servers for each site (each server must have an identical Code name across all sites), and set the CMSStagingTreatServerNamesAsInstances key to true. When a global staging task is synchronized, the system then automatically deletes the task from servers with matching code names on the other sites.

The default value is false because code name collisions may occur for staging servers on unrelated sites.

<add key="CMSStagingTreatServerNamesAsInstances" value="true" />

false

CMSStagingServerName

Name of the staging server used for advanced bi-directional content staging. The value needs to be used as the code name when defining this server as a target server of other servers.

See Bi-directional content staging for more information.

<add key="CMSStagingServerName" value="server2" />

“” (empty string)

CMSStagingServiceTimeout

<add key="CMSSynchronizeSharedTemplatesWithDocuments" value="false" />

true

CMSStagingUseTreeCustomHandlers

If true, events from the DocumentEvents class are raised when processing page staging tasks.

<add key="CMSStagingUseTreeCustomHandlers" value="false" />

true

CMSStagingLogGlobalObjectsOnlyForAssignedSites

If true, tasks for global objects are logged only for the sites to which the respective objects are assigned.

<add key="CMSStagingLogGlobalObjectsOnlyForAssignedSites" value="true" />

false

CMSStagingUseAutomaticOrdering

Determines whether the system applies automatic ordering to pages created via staging. If true (by default), the system overrides the ordering of new pages according to the Content -> Content management -> New page ordering setting.

<add key="CMSStagingUseAutomaticOrdering" value="false" />

true

CMSCIEncoding

Sets the character encoding used when the continuous integration solution generates non-binary files in the project’s CIRepository folder. The key supports values matching the encoding names listed in the Encoding Class article.

Changing the value of the CMSCIEncoding key does not update the encoding type of existing files in the CIRepository folder. To fully update the encoding of the repository content, you need to:

• Run complete serialization for all objects.
• Manually update the encoding type of your repository.config file.

<add key="CMSCIEncoding" value="utf-16" />

utf-8

CMSCIRepositoryPath

Sets the location of the continuous integration file repository root folder. The key’s value must be an absolute or relative path of a folder on a local drive, or a network location for which the application has sufficient permissions.

The specified location is used when serializing object data to the file system and when restoring data back to the database. The key also allows you to set a shared continuous integration repository if you have multiple projects with the same database (for example when developing MVC websites).

<add key="CMSCIRepositoryPath" value="C:\ExternalSourceControl\CIRepository" />

App_Data\CIRepository

CKEditor:DefaultToolbarSet

Allows you to set the default toolbar when you use the ‘default’ option for toolbar sets on a page. You can specify one of the following values:

All languages are enabled by default.

<add key="CMSEnableSyntaxHighlighting.CSS" value="false" />

true

CMSShowLineNumbers

Determines whether the code editor in the administration interface displays the panel containing line numbers by default.

Note: The editor fields used in the Kentico administration interface always have line numbers disabled by default. The key only affects custom fields that have displaying of line numbers enabled (fields using the Macro editor form control with the Show line numbers parameter enabled).

<add key="CMSShowLineNumbers" value="false" />

true

CMSUseMetaFileForProductImage

Indicates if meta files should be used for product images.

If set to true, the system asks the user, while creating or editing a product (or a product option), to select a product image from the file system on their computer. The system then uploads the product image to a server and saves it as a product metafile (a product image page of the cms.file type is not created). The path to this metafile is saved as the product image path (SKUImagePath).

If set to false, the system asks the user to select a page of the cms.file type as a product image. The path to the selected page is saved as the product image path (SKUImagePath).

<add key="CMSUseMetaFileForProductImage" value="true"/>

true

CMSUseStrictInventoryManagement

Products that use inventory tracking and have the Sell only if items available property enabled may be sold even when the inventory is depleted in cases where multiple customers place orders concurrently. By default, the system logs a warning into the event log if such a situation occurs.

If you set the key to true, the system throws an InvalidOperationException when a customer attempts to create an order containing a product that became out-of-stock due to another concurrently placed order.

The default checkout web parts on Portal Engine sites automatically handle the exception and display an error message.

If you wish to enable the CMSUseStrictInventoryManagement key on an MVC site or a Portal Engine site with custom checkout components, you need to manually ensure that your custom code handles the exception and displays appropriate information to customers.

<add key="CMSUseStrictInventoryManagement" value="true"/>

false

CMSEmailTransferEncoding

Specifies the type of transfer encoding used for emails sent from Kentico.

Supported values are: base64, quotedprintable, sevenbit

<add key="CMSEmailTransferEncoding" value="QuotedPrintable" />

base64

CMSEmailDeleteBatchSize

If the Settings -> System -> Emails -> Archive emails (days) setting is greater than 0, the system stores sent emails for the specified number of days, and regularly deletes them via the Clean email queue scheduled task. The CMSEmailDeleteBatchSize key sets the batch size for the number of emails deleted within a single database operation. The default value is 2000.

You can set a different value if you encounter related database performance issues or timeout errors. For example if you have a database server with relatively low performance and your instance contains a very large number of sent and archived emails.

<add key="CMSEmailDeleteBatchSize" value="200" />

2000

CMSEmailSendLimit

Sets the maximum number of messages sent to individual SMTP servers in a single connection. When the limit is reached, the connection is automatically closed and a new one opens. The process continues until all messages are sent.

You can lower the value if you encounter SMTP errors with too many messages set per connection.

<add key="CMSEmailSendLimit" value="20" />

50

CMSLogEmails

Enables logging of all sent emails to the ~/App_Data/logemails.log file.

The log contains each email’s timestamp, recipients, sender, subject, and custom headers and their encoding (UTF-8 by default).

<add key="CMSLogEmails" value="true"/>

Depends on debugging settings

CMSDebugEmails

Disables sending emails to the actual recipients. The system only logs emails into the event log. Helpful if you need to test the functionality, but do not want the emails to actually reach the recipients.

• To view the event log, open the Event log application.
• The emails are logged as Information type events.
• The Event code column contains the recipient’s address.
• The system randomly generates Sending failed for <recipient’s email address> errors to simulate sending errors.

<add key="CMSDebugEmails" value="true"/>

false

CMSEmailUtmParametersForAllLinks

If true, UTM parameters are added into all links in marketing emails, including external links. As opposed to the default behavior with enabled UTM tracking, when only relative email links (relative to your current site) are tagged by the specified UTM parameters.

In order for this key to work, you also need to always enable UTM tracking for a particular newsletter or email campaign.

<add key="CMSEmailUtmParametersForAllLinks" value="true"/>

false

CMSLogEvents

Indicates if logging of events in the Event log is enabled.

<add key="CMSLogEvents" value="true"/>

true

CMSLogKeepPercent

Coefficient for Event log deletion. Keeps the specified percentage of extra log items in the log with regards to the Settings -> System -> Event log size setting. The specified percentage of the oldest events is deleted by batch when the percentage is exceeded. If 0, the exact number of records is kept in the log.

<add key="CMSLogKeepPercent" value="10"/>

10

CMSLogEventsToFile

If true, events are also logged into the ~\App_Data\logevents.log file.

<add key="CMSLogEventsToFile" value="true"/>

false

If true and the Settings -> System -> Log metadata changes option is enabled, details about particular object changes are included in the respective log records.

<add key="CMSLogFieldChanges" value="true"/>

false

CMSLogDocumentFieldChanges

If true and the Settings -> System -> Log metadata changes option is enabled, details about changes of values in page fields are included in the respective log records.

<add key="CMSLogDocumentFieldChanges" value="true"/>

false

CMSLogNewsletterIssueEvents

Indicates if the system logs marketing email changes into the event log (including logging of all sent issues).

You can disable logging of these events if you encounter problems with performance or a cluttered event log when mailing issues to a very large number of recipients – subscribed contacts.

<add key="CMSLogNewsletterIssueEvents" value="false" />

true

CMSLogMATransitions

Indicates if the system logs all step transitions in Marketing automation processes into the event log.

You can disable logging of these events if you encounter performance issues or a cluttered event log when running automation processes for a very large number of contacts.

<add key="CMSLogMATransitions" value="false" />

true

CMSDataExportTemplateFolder

Indicates the starting path for template lookup.

<add key="CMSDataExportTemplateFolder" value="~/App_Data/CMSModules/DataExport"/>

~/App_Data/CMSModules/DataExport

Specifies which folders are filtered from the Files folder of the export package.

.svn folders are excluded by default, even without this key added.

<add key="CMSExportExcludedFolders" value="test*;cms*" />

CMSExportExcludedFiles

Specifies which files are filtered from the Files folder of the export package.

.scc files are excluded by default, even without this key added.

<add key="CMSExportExcludedFiles" value="test*;cms*" />

CMSSiteUtilsFolderPath

Overrides the default ~/CMSSiteUtils/ location where the system stores export and import packages by default. As a value, you can use:

• physical disk path - e.g. c:\myfiles\mysite
• virtual path - e.g. ~/UploadedFiles
• UNC path - e.g. \\server\folder

<add key="CMSSiteUtilsFolderPath" value="\\server\MyCustomFolder" />

CMSDefaultListingFilterLimit

Determines the minimum number of items that must be included in a listing in order for a filter to be shown. If the number of listed items is lower than this value, the filter is not displayed. If it is larger, the filter is displayed. This applies to all listings (UniGrid controls) across the entire UI.

<add key="CMSDefaultListingFilterLimit" value="40" />

25

CMSDefaultPageSizeOptions

Sets the options available in the page size selector for listings in the Kentico interface (the Items per page setting). Values must be separated by commas.

You can use the ##ALL## value to add an option that lists all available rows on a single page (not recommended if you have objects with a very large number of records).

<add key="CMSDefaultPageSizeOptions" value="10,50,200" />

5,10,25,50,100

CMSDefaultListingPageSize

Sets the initial page size of listings in the Kentico interface (the Items per page setting). If the value is not included among the options defined by the CMSDefaultPageSizeOptions key, the system automatically inserts the value as an additional option.

<add key="CMSDefaultListingPageSize" value="50" />

25

CMSListingShowFirstLastButtons

If true, the first and last page link buttons are included in the pagers of listings in the administration interface (with a large enough number of items). If false, the buttons are always hidden.

<add key="CMSListingShowFirstLastButtons" value="true" />

false

CMSListingShowDirectPageControl

If true, a text box that allows the current page to be changed by directly entering a number is included in pagers of listings in the administration interface (with a large enough number of items). If false, the control is always hidden.

<add key="CMSListingShowDirectPageControl" value="false" />

true

CMSUseCultureForBestPageInfoResult

Indicates whether the currently selected culture should have the highest priority when deciding which language version of a page should be displayed.

The default value is false, which means that accessing a page through the custom URL set for one of its specific culture versions will override and change the preferred culture accordingly.

If set to true, the currently selected culture will be reflected even when a culture‑specific page URL path is used.

<add key="CMSUseCultureForBestPageInfoResult" value="true" />

false

CMSLanguageParameterName

Changes the name of the query string parameter used to set the culture. For example, this allows you to get Home?sprache=de-de instead of the default Home?lang=de-de.

<add key="CMSLanguageParameterName" value="sprache" />

lang

CMSAliasPathParameterName

Changes the name of the aliaspath query string parameter so that you get products.aspx?ap=/products/myproduct instead of the default products.aspx?aliaspath=/products/myproduct.

<add key="CMSAliasPathParameterName" value="ap" />

aliaspath

CMSUseAutomaticScheduler

Indicates if the system uses automatic scheduling. When enabled, the scheduler periodically requests the ~/CMSPages/Scheduler.ashx route, which ensures that scheduled tasks are processed regularly even if there is no website activity.

If disabled (false - by default), tasks are processed at the end of standard page requests.

<add key="CMSUseAutomaticScheduler" value="true" />

false

CMSRunSchedulerWithinRequest

If true (the default value), the scheduler is executed within the standard EndRequest event of a page. If false, the scheduler is executed via the ~/CMSPages/Scheduler.ashx route.

<add key="CMSRunSchedulerWithinRequest" value="false" />

true

CMSSchedulerURL

Sets the URL used by the automatic scheduler. Must target the ~/CMSPages/Scheduler.ashx route or the URL of a fully custom scheduler.

<add key="CMSSchedulerURL" value="https://domain/cmspages/scheduler.ashx" />

~/CMSPages/Scheduler.ashx

CMSSchedulerAcceptAllCertificates

If true, all security certificates (including not valid ones) will be accepted when accessing the ~/CMSPages/Scheduler.ashx route via a secured protocol.

<add key="CMSSchedulerAcceptAllCertificates" value="true" />

false

CMSSchedulerUserName

Sets the user name under which the ~/CMSPages/Scheduler.ashx route is accessed (e.g. when using windows authentication).

<add key="CMSSchedulerUserName" value="office\myname" />

“” (blank username)

CMSSchedulerPassword

Sets the password for the user name under which the ~/CMSPages/Scheduler.ashx route is accessed.

<add key="CMSSchedulerPassword" value="mypassword123" />

“” (blank password)

CMSProcessContactActionsInterval

Sets the interval (in seconds) in which contact activities are batch processed by the system. Consider raising the interval if your system processes a large number of activities.

<add key="CMSProcessContactActionsInterval" value="30" />

10

CMSCreateContactActionsLogWorker

If enabled, all web farm servers recalculate contact scores, contact groups, personas, and marketing automation triggers.

If you wish to improve performance, you can set this key to false for one or more of your web farm servers, and the recalculation will be disabled for them.

Note: If you set the key value to false for all of your web farm servers, the recalculation will be disabled completely.

<add key="CMSCreateContactActionsLogWorker" value="false"/>

true

CMSGeoIPLocationFileName

Sets the name of the database file used by the geolocation feature for contacts. The file must be placed in the ~/App_Data/CMSModules/WebAnalytics/MaxMind/ folder of your web project.

<add key="CMSGeoIPLocationFileName" value="GeoIP2-City.mmdb" />

GeoLite2-City.mmdb

CMSAcceptAllCertificates

Indicates whether application requests should accept all certificates (including invalid certificates). This key ensures the same as if the following keys were enabled at the same time:

• CMSSearchCrawlerAcceptAllCertificates
• CMSSchedulerAcceptAllCertificates
• CMSStagingAcceptAllCertificates

<add key="CMSAcceptAllCertificates" value="true"/>

false

CMSAdminEmergencyReset

Allows you to recover access to the administration interface if you forget the password of your administrator account. The value must consist of the following parts, separated by semicolons:

• Username of the account
• New password for the account
• Optional true/false value which specifies whether you want to create a new user with the Global administrator privilege level.

The system automatically deletes the key after you gain access to the administration interface.

See also: Enabling password resets

<add key="CMSAdminEmergencyReset" value="admin;password;true" />

CMSAllowOnlySimpleMacros

If true, only simple macros (i.e. those which do not need a security check) are allowed. All others will not be resolved. If true, CMSTextBox control does not add security signatures to macros.

<add key="CMSAllowOnlySimpleMacros" value="true"/>

false

CMSEnableClickjackingProtection

Note: This key only applies to sites built using the MVC development model, and must be added to the web.config file of your MVC live site application.

When set to false, the key disables the Content Security Policy (CSP) headers that specify the frame-ancestors policy for the HTTP responses of preview mode requests on content-only sites. Only disable the key if you want to configure adding of CSP headers on your own (otherwise preview URLs would be susceptible to clickjacking attacks).

See also: Adding preview mode support

<add key="CMSEnableClickjackingProtection" value="false"/>

true

CMSEnableCsrfProtection

Indicates whether the system uses security tokens to protect Portal Engine pages against Cross site request forgery attacks. Only set this key to false if you have your own security mechanism against CSRF.

<add key="CMSEnableCsrfProtection" value="false" />

true

CMSEnableWIF

Overwrites the setting of the Enable WIF authentication option in Settings -> Security & Membership -> Authentication -> Claims-based authentication.

If included in the web.config file and set to false, this key can override enabled WIF authentication in case you have not established an administrator account (as described in Claims-based authentication) and you do not have access to the administration interface.

<add key="CMSEnableWIF" value="false"/>

CMSPasswordSalt

The password salt is a string that is appended to user passwords before they are hashed (to improve security). By default, the salt contains the randomly generated GUID of the given user. The content of this key is added after the base salt value to further increase the length of the salt.

Only applies if the application stores passwords using the SHA2 with salt format, which you can configure in Settings -> Membership & Security -> Passwords -> Password format.

See also: Setting the user password format

<add key="CMSPasswordSalt" value="SaltText" />

CMSPreviewLinkExpiration

Hotfix 12.0.47 (or newer) introduces an expiration time for the administration interface URLs used internally in the Pages application for the preview and page builder editing mode of pages on MVC sites. The URLs contain a timestamp parameter and expire after 8 hours by default.

You can use this key to adjust the expiration time. The key’s value is in minutes.

The key must be added to the web.config file of the Kentico administration application (not the MVC live site application).

<add key="CMSPreviewLinkExpiration" value="240" />

480

CMSRenewSessionAuthChange

When set to true, the system enforces a change of the session ID when a user signs in or out. Provides protection against session fixation attacks.

If you enable this key, users cannot preserve their session data after signing in or out.

See also: Session protection

<add key="CMSRenewSessionAuthChange" value="true" />

false

CMSXFrameOptionsExcluded

Excludes Portal Engine pages under the specified paths from clickjacking protection. For pages under the excluded path, the system no longer adds the X-frame-options: SAMEORIGIN header to the HTTP response (this header ensures that pages displayed in frames must originate on the same server as the parent page).

To exclude multiple paths, enter values separated by semicolons (;).

See also: Clickjacking protection

<add key="CMSXFrameOptionsExcluded" value="/Services" />

CMSUserBasedFloodProtection

Indicates whether the flood protection mechanisms are based on user accounts.

<add key="CMSUserBasedFloodProtection" value="true"/>

true

CMSSearchIndexPath

Sets the path of a custom directory where the system stores smart search index files (only applies to local search indexes).

<add key="CMSSearchIndexPath" value="App_Data\MyCustomIndexes" />

CMSCrawlerAllowSiteAliasRedirect

By default, Page crawler search indexes read pages that use redirection from the site’s main domain name to a domain alias. Setting this key to false only allows indexing for pages that use the website’s main domain.

<add key="CMSCrawlerAllowSiteAliasRedirect" value="false" />

true

CMSCreateTemplateSearchTasks

If enabled, any changes made to page templates automatically trigger an update of all pages that are based on the given template in the appropriate smart search indexes. The default value is true.

You can set this key to false if you wish to improve the performance or save resources in scenarios where you have a very large number of pages on your website that share the same page template. This way, the system no longer performs bulk updates of pages in the search index whenever their template is modified.

Disabling this key means that your page index will not reflect changes to the page template (e.g. if you add static text to the template through a web part) until the given pages are updated for another reason, or the entire index is rebuilt.

The key only affects changes to page templates. Editing the content of editable regions on a specific page always causes an update of the search index content.

<add key="CMSCreateTemplateSearchTasks" value="false" />

true

CMSProcessSearchTasksByScheduler

By default, the smart search creates and runs local indexing tasks immediately whenever content covered by a search index is created or modified.

If you set this key to true, the system does NOT run indexing tasks upon creation — they need to be processed periodically, typically using the Execute local search tasks scheduled task.

Note: The key does not affect processing of tasks for Azure search indexes. Azure search tasks are always processed by the Execute Azure search tasks scheduled task.

<add key="CMSProcessSearchTasksByScheduler" value="true" />

false

CMSSearchCrawlerAcceptAllCertificates

By default, the smart search crawler does not index pages on sites using a secured protocol (HTTPS) without a certificate from a trusted authority. For example, you may encounter the problem in development environments that use a self-signed certificate.

If you set this key to true, the system accepts all certificates.

Note: Setting the CMSSearchCrawlerAcceptAllCertificates key to true poses a security vulnerability and should not be used in production environments.

<add key="CMSSearchCrawlerAcceptAllCertificates" value="true" />

false

CMSSearchMaxFieldLength

Sets the maximum number of terms that the smart search allows in a single index field.

<add key="CMSSearchMaxFieldLength" value="10000" />

Unlimited

CMSSearchMaxResultsNumber

Sets the maximum number of results that the smart search can return for a single search request, when using local search indexes. If a search produces more matching results, the system ignores the items that do not fit into the limit.

The purpose of the limit is to avoid processing of large numbers of search results with low relevance. If you use very large search indexes that regularly produce more than 1000 results (the default limit), you can either increase the value or set up search filters to help narrow down the search.

Important: The key may not apply on MVC sites (depending on your search implementation) or for custom searches built using the API. The maximum number of search results is overriden by the NumberOfProcessedResults property of the SearchParameters object that you use to perform the search. If you create the search parameters using the SearchParameters.PrepareForPages method, the default number of processed results is 100.

<add key="CMSSearchMaxResultsNumber" value="3000" />

1000

CMSSearchSynonymsWeight

Sets the relevance (result score) that the search assigns to items found through the synonym search (i.e. when using Any word or synonyms search mode).

The key’s value must be a decimal number ranging from 0 to 1. A larger number assigns higher relevance to synonyms. If you set 1, the score of synonyms is equal to words in the original unexpanded search expression.

Only applies when using local search indexes.

<add key="CMSSearchSynonymsWeight" value="0.8" />

0.9

CMSSmartSearchLockPollInterval

Specifies how often (time in milliseconds) the smart search indexer attempts to acquire a lock on index files (for local indexes).

The default value of this key is 500 milliseconds.

Set a lower value if the following exception is being logged in your Event log.

Lock obtain timed out: CMS.SiteProvider.SearchLock

<add key="CMSSmartSearchLockPollInterval" value="300" />

500 ms

CMSSmartSearchLockTimeout

Defines the timeout period (in milliseconds) during which the smart search indexer attempts to acquire a lock on index files (for local indexes).

The default value of this key is 1000 milliseconds.

<add key="CMSSmartSearchLockTimeout" value="1500" />

1000 ms

CMSSubsetAnalyzerWordRegex

Sets a regular expression that determines which characters are allowed in the “words” processed by local search indexes with Subset and Starts with analyzers.

The analyzers use the following steps to create search tokens:

1. Divide text into words
2. Tokenize the substrings inside the words (according to the analyzer type)

The words created in the first step may contain only characters that match the regular expression in the key’s value. Any other characters split the text into separate words.

By default, the following characters are allowed:

• word characters (upper and lower case letters, numbers, underscores)
• at symbols (@)
• periods ( . )

<add key="CMSSubsetAnalyzerWordRegex" value="(\w|@|\.|\$)+" />

(\w|@|\.)+

CMSSearchStoreContentField

Determines whether the smart search stores the original untokenized Content field within index files.

Warning: Setting the key to true reduces indexing performance and increases the size of index files (the difference can be GBs of data for very large indexes). Only enable the key if you need to inspect or debug the content of your index files on development sites. Never enable the key on production sites.

<add key="CMSSearchStoreContentField" value="true" />

false

CMSAzureSearchDnsSuffix

Modifies the domain suffix appended by the system to requests sent to Azure Search.

By default, the system assumes Azure Search services are hosted on the search.windows.net domain. This key overrides the default behavior, allowing you to specify a custom domain suffix. This can be useful, for example, when running search services on Azure Government subscriptions, which are hosted with the search.azure.us domain suffix.

<add key="CMSAzureSearchDnsSuffix" value="search.azure.us" />

search.windows.net

CMSSearchDetectTextEncoding

Indicates whether the attachment search uses automatic detection of character encoding for text files (txt and csv).

By default, the search can read text files that use the following encoding:

• UTF-8
• The default Windows encoding (the operating system’s current ANSI code page)

If you enable automatic detection, the system attempts to detect the encoding type for each file, and use the correct option when reading the content.

Note: Correct encoding detection is not guaranteed for all files. Automatic detection also slightly increases the time required to index text files.

<add key="CMSSearchDetectTextEncoding" value="true" />

false

CMSSearchIndexXmlAttributes

Determines whether the attachment search includes the values of tag attributes when indexing XML files.

<add key="CMSSearchIndexXmlAttributes" value="true" />

false

CMSSearchIndexXmlComments

Determines whether the attachment search includes comments when indexing XML files.

<add key="CMSSearchIndexXmlComments" value="true" />

false

CMSSearchMaxAttachmentSize

Sets the maximum allowed file size in kB for the attachment search. The search ignores page attachments whose size exceeds the value.

Indexing very large files can be resource intensive and have a negative impact on your website’s performance.

<add key="CMSSearchMaxAttachmentSize" value="10000" />

0 (unlimited)

CMSTranslationServicesUseCDATAForTransUnit

Use if you want to export XLIFF files without the CDATA notation.

<add key="CMSTranslationServicesUseCDATAForTransUnit" value="false" />

true

CMSTranslationsUseAbsoluteLinks

Determines whether the URLs in content sent for translation are converted to absolute format. If true, the links in content sent for translation are absolute and not converted back to relative format when the translated content is imported back to the system.

Note that using absolute links in content sent for translation can cause issues when, for example, synchronizing the imported translation to a different domain by staging.

<add key="CMSTranslationsUseAbsoluteLinks" value="true" />

false

CMSDefaultSpellCheckerCulture

Specifies the default culture of the built-in spell-checker. This culture is used when the dictionary for the currently selected content culture is not found.

<add key="CMSDefaultSpellCheckerCulture" value="en-US" />

en-us

CMSShowLogonCultureSelector

Indicates if the user interface sign-in page should display a drop-down list with available user interface languages.

<add key="CMSShowLogonCultureSelector" value="false" />

true

CMSDefaultUICulture

Specifies the default UI culture.

If you use this key, you also need to:

1. Add a corresponding resource string file (localization pack) into the ~\CMSResources folder.
2. Rename the default CMS.resx file to CMS.en-us.resx.
3. Rename the new culture’s resource string file to CMS.resx.

This is needed because the CMS.resx file is used when the (default) option is selected as a user’s Preferred user interface culture.

<add key="CMSDefaultUICulture" value="en-nz"/>

en-us

CMSUseSQLResourceManagerAsPrimary

Changes the priority of used localization resource strings to:

1. custom.resx
2. cms.resx
3. database (Kentico administration -> Localization application)

<add key="CMSUseSQLResourceManagerAsPrimary" value="false" />

true

CMSWebAnalyticsRemoveReferralQuery

Indicates whether URL query strings are removed when logging Referrals and Referring sites in web analytics. When false, the system then no longer aggregates Referrals and Referring sites from the same source with different query string parameters into a single URL.

<add key="CMSWebAnalyticsRemoveReferralQuery" value="false"/>

true

CMSWebFarmMode

Indicates if web farms are:

• disabled
• automatic – no further configuration is needed.
• manual – requires manual configuration of web farm servers in the system.

<add key="CMSWebFarmMode" value="automatic"/>

disabled

CMSInstanceNameSuffix

When using Automatic web farm mode, the system generates the names of servers by combining the machine name and virtual directory in which the application is running. You can use this key to set an additional suffix that is added to the automatic server name for the given instance.

If you do not set a custom value, the system automatically uses the AutoExternalWeb suffix for external web applications running the Kentico API (typically MVC live site applications).

“” (empty string)
– or –
AutoExternalWeb

CMSWebFarmServerName

Code name of the web farm server. This value is used for manual web farm synchronization support.

This setting overrides the name assigned by the system in Automatic web farm mode.

<add key="CMSWebFarmServerName" value="server1" />

“” (empty string)

CMSWebFarmMaxFileSize

If the CMSWebFarmSynchronizeFiles key is enabled, you can limit the maximum size of synchronized files using this key. The value is entered in kiloBytes and files larger than this value will not be synchronized.

<add key="CMSWebFarmMaxFileSize" value="1024" />

2147483647 (int.MaxValue)

CMSWebFarmApplicationPhysicalPath

Path to the application on the disk used for synchronizing physical files.

<add key="CMSWebFarmApplicationPhysicalPath" value="C:\inetpub\wwwroot\Kentico" />

CMSWebFarmSyncInterval

Average time before a created web farm synchronization task is processed by web farm servers (the maximum possible time before a task is processed is double of the specified interval).

<add key="CMSWebFarmSyncInterval" value="100" />

2000 ms

CMSWebFarmSynchronizeFiles

Determines if web farms synchronize files in general. This key enables synchronization of:

• Attachments
• Meta files
• Media files
• Form files
• Avatars
• Forum attachments

Microsoft Azure notes:

The key is false by default for projects running in Microsoft Azure Cloud Services.

For projects hosted in Microsoft Azure Web Apps, we strongly recommend that you manually set the key to false. Otherwise, you may encounter file system collisions when scaling to multiple instances.

<add key="CMSWebFarmSynchronizeFiles" value="false" />

true

CMSWebFarmTaskDeleteBatchSize

The system regularly performs cleanup of unnecessary web farm synchronization tasks (orphaned tasks without a related web farm server, etc.). The key sets the batch size for the number of tasks deleted within a single database operation. The default value is 500.

You can set a different value if you encounter related database timeout errors, for example if you have a database server with relatively low performance and your instance contains large synchronization tasks with binary data.

<add key="CMSWebFarmTaskDeleteBatchSize" value="100" />

500

CMSAzureProject

Must be set to true if you wish to run the application in Microsoft Azure Cloud Services.

True by default if the application is installed as a Microsoft Azure project, false in standard installations.

<add key="CMSAzureProject" value="true"/>

CMSAzureAccountName

Specifies an amount in gigabytes that is used by theClean Azure storage cachescheduled task. The amount is the target size of the Azure Cache and Azure Temp folders when the scheduled task deletes the files.

The size of the excluded paths (set by the CMSAzureStorageCacheCleanerExcludedPaths web.config key) is included in the amount.

The default value is 10GB.

<add key="CMSAzureStorageCacheCleanerKeepLimit" value="10"/>

CMSAzureStorageCacheCleanerExcludedPaths

<add key="CMSAzureCDNCacheMinutes" value="30"/>

CMSAzureTempPath

The folder specified by this key will be used to store temporary files on a local disk, e.g. when transferring large files to or from the storage account.

Do not use this key if the entire application is deployed as a Microsoft Azure hosted service.

<add key="CMSAzureTempPath" value="C:\AzureTemp" />

CMSAzureCachePath

Specifies a folder on a local disk where files requested from the storage account will be cached. This helps minimize the amount of blob storage operations, which saves time and resources.

Do not use this key if the entire application is deployed as a Microsoft Azure hosted service.

<add key="CMSAzureCachePath" value="C:\AzureCache" />

CMSDownloadBlobTimeout

Specifies the timeout interval in minutes for importing files from Azure Blob storage into Kentico.
