Initializes a new instance of the CHttpModule class.
CHttpModule (
); This method takes no parameters.
The constructor for the CHttpModule class is protected to prevent the direct creation of a CHttpModule class. You must create a class that is derived from CHttpModule, because CHttpModule defines pure virtual methods that derived classes must implement.
The following code example demonstrates how to create a request-level HTTP module that registers for the RQ_BEGIN_REQUEST event notification. When a request enters the integrated request-processing pipeline, IIS will call the example module's OnBeginRequest method. This method will write an entry in the application log of the Windows Event Viewer that contains "Hello World!" in the event data. 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.
