Subject: Re: Corrupted GIFs through proxy.
The problem is well-known from other situations but I have not seen it
with gif-files. Its is due to the reaction of a 0.9 server when talking
to Mosaic (the TCP window gets filled up with no ACKs sent back). I have
explained the symptoms at the page
http://info.cern.ch/hypertext/WWW/Daemon/Bugs.html
which I use to explain known bugs or eqivalent information. Currently
there is little to do as the HTTP protocol can't change the status code
on the fly.
The quick solution is - get a new server!
