[squid-users] POST + NTLM Authentication

Guys,

We have a squid-2.5STABLE14 with NTLM authentication.

I note that when you try to upload a file on 4shared.com or
in.solit.us, it begins well but after some seconds, appears a pop-up
window asking for user and password. Ok, I write those things and
browser (even IE or Firefox) hangs.

PS: It works when I use an direct connection (without proxy).
