IHttpCachePolicy::SetIsCached Method

  • Article

 

Sets a value that indicates that the data is cached.

Syntax

virtual VOID SetIsCached(  
   VOID  
) = 0;

Parameters

This method takes no parameters.

Remarks

CHttpModule derived classes that register for request or response events receive an IHttpContext pointer as a parameter on the corresponding virtual method. To enable caching, call the IHttpContext::GetResponse method, the IHttpResponse::GetCachePolicy method, and finally the SetIsCached method.

SetIsCached behavior depends on implementation. You should use the following information as a guideline, but it may not be correct in all scenarios:

  • The current default implementer of the IHttpCachePolicy interface declares a private Boolean value that is initialized to false at construction. When SetIsCached is called, this Boolean value is set to true. After SetIsCached is called, there is no method to reset this Boolean value to false.

  • SetIsCached returns the value of this Boolean.
