Not for a very long time. Back then it was a server sending responses
that said it had no payload attached.

You can set "debug_options All,0 11,2" in squid.conf to get a cache.log
trace of the HTTP message headers going through Squid. If you can post
here the headers titled "HTTP Server REPLY" which are coming in from the
Cisco on these transactions it would help us debug with you.
