CHttpModule::OnReleaseRequestState Method

IIS 7.0
 

Represents the method that will handle a ReleaseRequestState event, which occurs when the current state is released.

virtual REQUEST_NOTIFICATION_STATUS OnReleaseRequestState(
   IN IHttpContext* pHttpContext,
   IN IHttpEventProvider* pProvider
);

pHttpContext

[IN] A pointer to an IHttpContext interface.

pProvider

[IN] A pointer to an IHttpEventProvider interface.

When a request-level module has registered for the RQ_RELEASE_REQUEST_STATE event notification, IIS will call the module's OnReleaseRequestState method when it releases the state for the current request.

System_CAPS_noteNote

Request-level modules can register for the ReleaseRequestState event notification by registering for RQ_RELEASE_REQUEST_STATE in the module's RegisterModule function.

Example

The following code example demonstrates how to create a request-level HTTP module that registers for the RQ_RELEASE_REQUEST_STATE event and post-event notifications. When IIS releases the state for the current request, it will call the example module's OnReleaseRequestState and OnPostReleaseRequestState methods. Each method will write an entry in the application log of the Windows Event Viewer. When processing is complete, the module will exit.

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.

You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
