debugging suggestions

Good morning all,
I'm developing a cgicc fastcgi application. I can serve regular html
pages just fine but when I try to do AJAX stuff it blows chunks
(that's a technical term). I'm using IIS with the fastcgi dll for
testing. My code is simple. I create a new httpresponse header and
populate it with '204' and 'No Content'. I send it and a text/plain
header. It looks like it matches the http 1.0
spec but I keep getting 500 errors from IIS. Any suggestions?
