PS. If it's not an intranet site and the URL isn't secret, it'd help
if we could actually try things out. One of the tricks I like to use
is to access the same page with a different program/library - maybe
wget, or bare telnet, or something like that. Sometimes one succeeds
and another doesn't, and then you dig into the difference (once I
found that a web server failed unless the request headers were in a
particular order - that was a pain to (a) find, and (b) work around!).
