Re: Which HTTP/1.1 features are not supported

IE only uses HTTP/1.1 and persistent connections thru proxies if asked
to... see Internet Options -> advanced somewhere..

Squid supports persistent connections using the "Proxy-Connection:
keep-alive" extension to HTTP/1.0. It also understands that HTTP/1.1 is
persistent by default, but since Squid is not yet fylly HTTP/1.1
compliant it cannot make much use of this fact.
