fully internally to Squid we have the X-Cache: header at present
being emitted with HIT/MISS details. You may be able to setup a
rep_header_regex ACL the scans for HIT and your upstream cache name.
Used on tcp_outgoing_tos to set TOS value. This is not a completely
reliable header though, there will be some false matches or failures
using it at present and future plans are to remove it from most
traffic.

Hi Amos, I think you should be talking about the clientside_tos
because this
is what I need (marking the packets from squid to users).
I had to patch my squid and recompile it because I was using 3.1.19
ubuntu
version, which had the bug - not working clientside_tos (thanks to
mailing
list I found info about it) - so I did it and clientside_tos feature
is now
working as a whole.
Now, I'm trying to setup a rep_header ACL but I got some errors like:
2012/05/07 13:13:20.795| ACL::checklistMatches WARNING: 'hit' ACL is
used
but there is no HTTP reply -- not matching.
So my packets are not marked...
here is part of the config:
acl hit rep_header X-Cache HIT
clientside_tos 0x30 hit
What does this error means?
It means the access control (clientside_tos) is being tested before a
response is available. It is tested when the request headers are
received and parsed, but before the request body is transferred.
Anyway I can solve this issue?
Someone needs to figure out how/where to re-test the ACLs and set the
TOS after response headers are received and before response body is
transferred to the client. This may be multiple places.
