Implements file based caching on the given page output.

Syntax

Smartsite SXML	Copy Code
<se:cachefile />

Parameters

Name	Data Type	Properties	Description
Enabled	Boolean	-	Sets a value indicating whether caching is enabled.
Expiration	DateTime	-	Sets the expiration date/time to compare with the cache entry on disk. When the specified expiration value exceeds the last modified value of the cached entry a new entry is written.
MaxAge	String	-	Sets the timeout in the format of a TimeSpan (00:00:00).
Transfer	Boolean	-	Sets a value indicating whether existsing cache should be transferred on execution.

Shared Parameters

Name	Data Type	Properties	Description
Access	String	-	Friendly name of the minimum access type level required by the site visitor to execute this macro.
AccessDenied	String	RawData	Sets the value that is returned when the site visitor has insufficient access.
AIM	Enum	-	Sets the AIM scanning mode of the macro. Enum values: NotSet Not set. Off No AIM scanning. External Output XML scanning. Internal Internal scanning, implemented by AIM-aware macros. Autonomous Relations are to be linked to the current source item, instead of the rendered page. SoftLink Should generate soft links (in combination with External flag). InternalAutonomous Internal scanning, combined with the Autonomous setting. ExternalAutonomous External scanning, combined with the Autonomous setting. ExternalAutonomousSoftLink External scanning, combined with the Autonomous and softLink settings. ExternalSoftLink External scanning, combined with the Softlink setting.
Condition	String	MustBeAttribute ExpressionSyntax XmlDecode	Sets the Viper expression to evaluate before actually executing the macro. If the expression returns false, the execution of the module and its child modules is skipped.
Default	String	RawData	Sets the default value that will be returned when the execution would otherwise return an empty string.
Error	String	RawData	Sets the value to return in case on error occurs during execution. The Viper expressions this.error(), this.error(full) and this.error(type) are available in this context.
Id	String	MustBeAttribute Trim	Sets the Id of the macro. Macros with Ids set can be accessed using Viper by referring to page.[id].[methodname()].
LocalId	String	MustBeAttribute Trim	Sets the local id of the macro in the current buffer scope.
Rem	String	RawData NoCache Trim	Sets the remarks. Remarks have no effect on the actual execution of the module. They only improve the readability of the code.
ResultFormat	String	RawData	Sets the resultformat.
ResultType	Enum	-	Sets the type of the result. Enum values: Undefined Not set None No result String Default type Object Generic object Binary Binary data Boolean Boolean DataTable DataTable DateTime Date/time Float Floating point numeric data Integer Integer Locator Extended Uri Xml Xml Data
Save	Collection	-	Sets the buffer names.
Status	Enum	-	Gets a value indicating the ModuleStatus of this module. Enum values: Unknown Unknown BeginInitialize Initializing the module EndInitialize Module has fully initialized BeginSetProperties Properties are about to be set EndSetProperties Properties have been set BeginExecute Execution starts BeginFormatData Starting data formatting. EndFormatData Ended data formatting. BeginFormatResult Before formating result. EndFormatResult After formatting result EndExecute Execution is ending StartLoseScope Execution has completed EndLoseScope Module is about to unload Error Module is in an error state
Timeout	Float	-	Sets the timeout in seconds. In the overriden Execute() method, you can call CheckTimeout() to check whether execution has timed out.
Trim	Enum	MustBeAttribute	Gets a value indicating how the whitespace is trimmed.
Whitespace	Enum	MustBeAttribute	Gets a value indicating whether to preserve whitespace. Enum values: Inherit Inherit from parent. Preserve Keep all whitespace. Remove Remove all whitespace. Normalize Convert all whitespace to single spaces. SimpleFormat Convert all whitespace to single spaces, but keep single line breaks.

This.Enable	✓	Enables the cache.
This.GetForcedResult		Gets the forced result of the macro, set by overriding the normal rendering using SetForcedResult().
This.Ignore	✓	Ignores the current cache file, but cache will be written after page execution.
