Hi:
I'm trying to replace the response that the web server (IIS) sends to a client via an ISAPI Filter.

I built using Visual Studio 2003. I built it with the ISAPI Extension Wizard (making it with filter options).

The problem here is that every time the browser ask for the htm page, the browser gets the the contents of the original htm page. But what i want is to change that content to some other content. So the WriteClient function seems to do nothing. How should i do this???

Here's part of my code.

DWORD CCodeHiderFilter::OnSendResponse(CHttpFilterContext* pfc, PHTTP_FILTER_SEND_RESPONSE pSendResponse)
{
      char strMensaje[40];
      sprintf(strMensaje,"<HTML><BODY>HELLO</BODY></HTML>");
    DWORD dwCont;
      dwCont = (DWORD)strlen(strMensaje);
      if(pfc->WriteClient(strMensaje, &dwCont) == 0)
      {
            GetLastError();
      }
      // TODO: React to this notification accordingly and
      // return the appropriate status code
      
      return SF_STATUS_REQ_NEXT_NOTIFICATION;
}

Thanks in advance
