I cannot upgrade at the moment because of the policy regarding this
particular infrastructure so I have to deal with this old copy of Squid.

either request or reply headers.

As I tried to explain if I use only Squid I see (tcpdump) the request
going out and the reply coming in and the browser is able to process the
page; if I enable dansguardian squid forward the bad header
(TCP_MISS/600) and dansguardian is not able to process the page.

I put the debug_options to ALL,9 and now we have lot of output, as the
Squid 600 code stated there's something wrong with the header, can you help?

-It seems that the mailing list is not accepting this mail if I attach
the 150k log file, anyway to send it?-

TIA.
