I'm writing an MFC isapi extension, running in IIS 5.0, Windows 2000.
How can I return HTTP error code (such as 404, 500 etc) in the HTTP header to the HTTP client.

to do that you have to write some extra call in the your
for example:
DWORD CMyExtension::HttpExtensionProc( EXTENSION_CONTROL_BLOCK *pECB ){

if (....) // some conditions
// Raize Access denied error
          strcpy(pECB->lpszLogData,"WWW-Authenticate: Basic Realm=\"Secure\"\r\n\r\n");

          size = lstrlen ( pECB->lpszLogData);
          pECB -> ServerSupportFunction ( pECB->ConnID,
                                        "401 Access Denied",
                                        (LPDWORD) pECB->lpszLogData );
          return HSE_STATUS_ERROR;
