This server violates the HTTP protocol in a peculuar manner, and is
rejected by Squid as the exact same violation to the protocol is used
for bad purposes in attempts to poison the cache with false information
for the purpose of defacing web sites, stealing traffic, stealing
banking information and more ugly things..

In theory Squid could work around the broken site by cleaning up the
response like it does for many other HTTP violations, but this has not
been implemented for this specific violation.

See cache.log for details on the specific protocol violation and the
response splitting and request splitting advisories and the whitepapers
referenced from there for more information on the security threats
involved in this protocol violation.
