CHttpModule::OnMapRequestHandler Method

Represents the method that will handle a MapRequestHandler event, which occurs when IIS maps the current request to an event handler.

Syntax

virtual REQUEST_NOTIFICATION_STATUS OnMapRequestHandler(  
   IN IHttpContext* pHttpContext,  
   IN IMapHandlerProvider* pProvider  
);

Parameters

pHttpContext
[IN] A pointer to an IHttpContext interface.

pProvider
[IN] A pointer to an IMapHandlerProvider interface.

Return Value

A REQUEST_NOTIFICATION_STATUS value.

Remarks

When a request-level module is registered for the RQ_MAP_REQUEST_HANDLER event notification, IIS will call the module's OnMapRequestHandler method when IIS maps the current request to an event handler.

Note

Request-level modules can register for the MapRequestHandler event notification by registering for RQ_MAP_REQUEST_HANDLER 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_MAP_REQUEST_HANDLER event and post-event notifications. When IIS maps a request to an event handler, IIS will call the example module's OnMapRequestHandler and OnPostMapRequestHandler methods. Each method will write an entry in the application log of the Windows Event Viewer. When processing is complete, the module will exit.

[!code-cppCHttpModuleMapRequestHandler#1]

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.
