That'll teach me to just rely on the output of squid -v. The squid RPM is a vendor package from Centos and there is a difference on the servers. One server is running auto updates so has the newest package but the other server has the next release down as it's not running auto updates. I've now updated the live server and it all seems to be fine now.

Even down to the options squid was compiled with, verified with "squid > -v". Are you really really sure about the above? Squid-2.5.STABLE6 does not even have the checks for this HTTP protocol violations this site trips on (this was added in 2.5.STABLE8 and refined in later versions), so I suspect you are not really running 2.5.STABLE6 but either a newer version or a vendor version having many backported patches.. If you are running a vendor version then verify that the vendor minor version of the squid package is indeed the same.. I.e. if it's a RedHat system verify "rpm -q -f /usr/sbin/squid" reports the same on both servers. I suspect isn't the same..
