Phew. I guess if we needed to I can alter our wpad.dat and policy filter
to dictate direct access to norton updates, though I'd really rather not.
I do see this sort of error in the logs occasionally.

Mar 26 11:17:50 proxy squid[2969]: parseHttpRequest: Invalid HTTP version
Mar 26 11:17:51 proxy squid[2969]: parseHttpRequest: Invalid HTTP version
Mar 26 11:17:54 proxy squid[2969]: parseHttpRequest: Invalid HTTP version

Actually that's from a different proxy server running Debian and
2.6.5-6etch4.

Does it help to tell the server you're using 1.1? Will the server not then
respond using 1.1 features which squid doesn't support?
