CHttpModule::OnLogRequest Method

IIS 7.0
 

Represents the method that will handle a LogRequest event, which occurs when IIS prepares to log the current request.

virtual REQUEST_NOTIFICATION_STATUS OnLogRequest(
   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 is registered for the RQ_LOG_REQUEST event notification, IIS will call the module's OnLogRequest method when IIS prepares to log the current request.

System_CAPS_noteNote

Request-level modules can register for the LogRequest event notification by registering for RQ_LOG_REQUEST 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_LOG_REQUEST event and post-event notifications. When IIS logs the current request, IIS will call the example module's OnLogRequest and OnPostLogRequest 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.
