> Description:
My ISAPI extension makes use of the CHttpServerContext::ServerSupportFunction to send \
a redirect message to the client (browser) using the HSE_REQ_SEND_URL_REDIRECT_RESP \
flag.  According to the MSDN documentation, this is supposed to always send a 302 \
status along with the target URL in the header of the response, allowing the client \
to get to the correct URL.  When I invoke my ISA with a request resulting in a \
HSE_REQ_SEND_URL_REDIRECT_RESP message, my client gets a status of 200.  The browser, \
as it should, thinks its work is done and I'm stuck on a blank page as the redirect \
does not occur.

When running my ISAPI extension on IIS, a 302 code is sent, allowing for the client \
to redirect.

If I use the HSE_REQ_SEND_URL flag instead of the HSE_REQ_SEND_URL_REDIRECT_RESP flag \
in my ISA, I get the expected results, as apache performs the redirect and only sends \
the client the final URL.
> How-To-Repeat:
My url looks like: http://server/scripts/myisapi.dll/Logon?...
The request is processed by the ISAPI extension and a redirect is sent for the target \
site.
> Fix:
I'm not familiar with the Apache code that handles the redirects (and possibly all \
responses), but I'd imagine there is a struct (or similar) that holds the information \
to respond with.  This struct should always be updated with the 302 return code when \
the HSE_REQ_SEND_URL_REDIRECT_RESP flag is sent to the ServerSupportFunction() \
method.
