Maybe IE7 does not play nice in some way and Apache can cope with
it but inets expects better behaviour somehow. I think we can only
make progress by seeing what's happening at a lower level. The http
conversation between the web server and browser might be a good place
to look. For details of how http works see the RFCs

http://www.faqs.org/rfcs/

maybe 2616 would be a good place to start

http://www.faqs.org/rfcs/rfc2616.html

(Perhaps you knew that, but maybe somebody else reading doesn't.)
If you could get a trace of http requests and responses and point
out the one that works followed by the one that fails that would be
the kind of information that might be interesting. Hope that helps.
