Description Robert Clark 2005-03-10 15:35:52 UTC 
This is with squid-2.5.STABLE3-6.3E.8

Squid doesn't cope with HTTP response headers which are split across different
TCP packets.

Observed proxying to http://www.iii.co.uk/
Produces the following error (intermittantly):

2005/03/10 10:59:01| WARNING: unparseable HTTP header field near {: Thu, 10 Mar
2005 10:58:59 GMT
Server: Apache/1.3.22 (Unix) AxKit/1.4_82 mod_perl/1.26 mod_gzip/1.3.19.1a
Vary: X-HOST
Expires: now
Pragma: no-cache
: no-cache,no-store,private
Content-Type: text/html
Content-Encoding: gzip
: 18064
}

The missing parts of the headers are being sent by the origin server but are
lost by squid.

This is a known issue and the patch to fix it is available at:
http://www.squid-cache.org/Versions/v2/2.5/bugs/squid-2.5.STABLE7-split_headers.patch

I've tested this and it applies cleanly to the current SRPM and fixes the problem.
