Clears the response entity.
virtual VOID Clear(
VOID
) = 0; This method takes no parameters.
VOID.
The Clear method empties the response contents, including the HTTP headers, the response body, and the HTTP status information. This method resets the response headers and body to default values.
Note
If the server has already flushed the response buffer to the client when you call the Clear method, the method may appear to have no effect.
The following code example demonstrates how to use the Clear method to create an HTTP module that clears the response headers and body and returns a default response to the client.
[!code-cppIHttpResponseClear#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.
