Hi, I'm trying to test the wildcard script map using the WildCardMap sample however the HttpExtensionProc function is never being invoked ... any idea ? I simply added the dll to the web service extensions and to the wild card application map (no filter yet). My goal is to use the extension as a filter. i.e. add to the dll HttpFilterProc and GetFilterVersion. Are both HttpFilterProc and HttpExtensionProc gonna be called ? Thanks, Gilad.
