Types of Metabase Properties

The isolation mode that is configured for your IIS application affects the way some properties behave, as described below.

Application-Level Properties

Application-level properties, when set, apply to the entire application regardless of the isolation mode in which your IIS server is running. Setting an application-level property in one location does not affect the entire application pool (see individual property topics for exceptions).

The following properties are application-level properties:

AppAllowClientDebug

AppAllowDebugging

AspAllowSessionState

AspAppServiceFlags

AspBufferingLimit

AspBufferingOn

AspCalcLineNumber

AspCodepage

AspEnableApplicationRestart

AspEnableParentPaths

AspExecuteInMTA

AspKeepSessionIDSecure

AspLCID

AspPartitionID

AspQueueConnectionTestTime

AspQueueTimeout

AspRunOnEndAnonymously

AspScriptErrorMessage

AspScriptErrorSentToBrowser

AspScriptLanguage

AspScriptTimeout

AspSessionMax

AspSessionTimeout

AspSxsName

Process-Level Properties

Process-level properties only have an effect on IIS behavior if they are set at the service level (for both isolation modes), or at the server level (for IIS 5.0 isolation mode, if the application is set to High isolation).

IIS 5.1 and earlier: Process-level properties only have an effect on IIS behavior if they are set at the server level and if the application is set to High isolation.

The property pages might list other locations where IIS allows you to set these properties, but they have no effect on IIS behavior.

The following properties are process-level properties:

AspAllowOutOfProcComponents

AspDiskTemplateCacheDirectory

AspEnableAspHtmlFallback

AspEnableChunkedEncoding

AspEnableTypelibCache

AspErrorsToNTLog

AspExceptionCatchEnable

AspLogErrorRequests

AspMaxDiskTemplateCacheFiles

AspProcessorThreadMax

AspRequestQueueMax

AspScriptEngineCacheMax

AspScriptFileCacheSize

AspTrackThreadingModel

For more detailed information about features and benefits of IIS 6.0 worker process isolation mode, see the "Web Application Isolation" topic in the IIS User Documentation.

Application Pool (Worker Process) Properties

Metabase properties, when set on an IIsApplicationPool or IIsApplicationPools admin object, require a recycle of the application pool.

IIS 5.1 and earlier: Application pool properties do not apply to versions of IIS previous to 6.0.
