Reference - Web.config application keys

CMSProgrammingLanguage

Indicates the programming language used in transformations and in custom code added to web parts.

Note: Existing transformations are not automatically rewritten to the new language. We only recommend changing the value before starting the project’s development phase.

<add key="CMSProgrammingLanguage" value="C#" />

or

<add key="CMSProgrammingLanguage" value="VB" />

C#

CMSTrialKey

Contains a temporary trial license key. You can remove this value after installation.

“” (empty string)

CMSHashStringSalt

Sets the salt value that the system uses in hash functions, for example when creating macro signatures. The installer automatically adds the key for new instances of Kentico, with a random GUID as the value.

Note: Changing the hash salt on a website that already has defined content may prevent macros from resolving correctly, or break dialog links and images on your website. If you encounter such problems, you need to re-save the given content or globally re-sign macros (the system then creates the hashes using the new salt).

<add key="CMSHashStringSalt" value="eb2d6fac-8b9e-427c-b98b-3c562dffbb35" />

Random GUID

CMSUseVirtualPathProvider

            </xs:restriction>
        ...
    </xs:element>
  
  
    

• Update any dependent objects. (E.g., View_CMS_Tree_Joined.)

Note: The maximum allowed length for the Node alias path is 450 characters, so the system may trim the alias path for pages deep in the content tree regardless of the allowed length.

<add key="CMSMaxNodeAliasLength" value="120" />

50

CMSMaxNodeNameLength

Warning: We do NOT RECOMMEND using this web.config key. Scenarios with a non-default value are not tested or supported.

If you use the key, you also need to manually update your Kentico database:

• Increase the size of the following database fields:

  • NodeName column in the CMS_Tree table
  • DocumentName column in the CMS_Document table
  • DocumentName column in the CMS_EventLog table
  • PageTemplateDisplayName column in the CMS_PageTemplate table
  • VersionDocumentName column in the CMS_VersionHistory table

• Change the size restriction of every column from the list above in its respective class (CMS.Tree, CMS.Document…) definition in the ClassXmlSchema column of the CMS_Class table.

  Copy

  
  
  
    <xs:element name="Name_of_the_field" minOccurs="0">
        ...
            <xs:restriction base="xs:string">
                <xs:maxLength value="100" />
            </xs:restriction>
        ...
    </xs:element>
  
  
    

• Update any dependent objects (E.g., View_CMS_Tree_Joined and IX_CMS_PageTemplate_PageTemplateCodeName_PageTemplateDisplayName).

<add key="CMSMaxNodeNameLength" value="150" />

100

CMSWebAnalyticsSlidingIPExpiration

This key is used when the Settings -> On-line marketing -> Web Analytics -> Remember visitors by IP (minutes) key has a value higher than 0.

If enabled, users who are active on the site but have disabled cookies are not logged as new visitors after the set time. If disabled, even an active user with disabled cookies is logged as a new site visitor after the set time.

<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" />

true

CMSRoleImportFormat

When the mixed mode authentication is used, this key determines the format of role names which are imported from Active Directory:

• SAM - the format of imported roles is rolename.
• DomainSAM - the format of imported roles is domain-rolename.

<add key="CMSRoleImportFormat" value="DomainSAM"/>

DomainSAM

CMSADDefaultMapUserName

When the mixed mode authentication is used, this key determines the format of user names which are used to communicate with the Active Directory provider:

• sAMAccountName - uses the Active Directory user name (without the domain).
• userPrincipalName - uses the Active Directory user principal name (e.g. MyName@office.example.com).

<add key="CMSADDefaultMapUserName" value="userPrincipalName" />

-

CMSEnsureSafeUserNames

Indicates if the system replaces forbidden characters in user names imported from Active Directory.

If the key is false, the system also uses less restrictive validation of users names for standard users (applies when new users register, or when creating or editing users in the administration interface). See the CMSUserValidationRegEx key for details.

<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

Sets the character that replaces forbidden characters in user names imported from Active Directory.

If not set, the value from Settings -> URLs and SEO -> Forbidden characters replacement is used.

<add key="CMSForbiddenUserNameCharactersReplacement" value="-" />

CMSForbiddenRoleNameCharactersReplacement

Sets the character that replaces forbidden characters in role names imported from Active Directory.

If not set, the value from Settings -> URLs and SEO -> Forbidden characters replacement is used.

<add key="CMSForbiddenRoleNameCharactersReplacement" value="-" />

CMSUserValidationRegEx

Sets a custom regular expression that determines which user names are valid. Applies when new users register on the website, are created in the administration interface or through the API, and when the name of an existing user is modified.

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

If the CMSEnsureSafeUserNames key is set to false, a less restrictive regular expression is used by default:
^[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. enter < instead of the < character.

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

CMSLimitUrlReplacements

CMSMediaFileMaxStagingSize

Sets the maximum size of media library files that are synchronized via staging (in kiloBytes). Add the key to the web.config file of projects that work as source servers in your staging environment.

The system does not synchronize binary data for media library files above the limit. Synchronization tasks for such files only transfer the database definitions of the media objects, without the actual files.

<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

Sets timeout interval for the service used to synchronize staging tasks. The key must be configured within the web.config file on the source instance from which the tasks are being synchronized.

<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

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" />

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.filetype 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.filetype as a product image. The path to the selected page is saved as the product image path (SKUImagePath).

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

true

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

<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

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

10

CMSCreateContactActionsLogWorker

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

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

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

• 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: Forgotten password

<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

CMSEnableCsrfProtection

Indicates whether the system uses security tokens to protect 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" />

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 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.

<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 ( . )

Note : After changing the value of the key, you need to Rebuild your search indexes that use Subset or Starts with analyzers.

<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

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"/>
