Re: [squid-users] Problem with authentication to IIS site for users behind squid proxy

G'day,

Squid-3.0 doesn't have the connection pinning support which proxying
NTLM requires.

I've deployed Squid-2.6 and Squid-2.7 in production at various
government / banking environments which use NTLM authenticated portal
sites to great success.
