Derived Classes

This interface contains no derived classes.


You can retrieve an IHttpUser pointer from an IHttpContext pointer by calling the IHttpContext::GetUser method. To gain access to these interfaces, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.


The following code example demonstrates how to create an HTTP module that clears the response headers and body and then returns user information to the client as an XML document.

The above code writes XML that is similar to the following to the response stream.

<?xml version="1.0" ?>  
    remoteName=" DOMAIN\user"   
    userVariable="NULL" />  

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.
