Hi, I have a problem while connecting to a site. I am using squid 3.1.4 The external web site is IIS and using NTLM authentication. If I try to connect this site (transparently), it is asking username and password. After entering correct username and password, It is asking user/pass again at firefox, at ie it is giving error. errors at squid access log; 1280398734.407 56 192.168.10.210 TCP_MISS/401 306 HEAD http://213.139.228.232/reports - DIRECT/213.139.228.232 But If I setup proxy definition to browser, everything is ok. access.log 1280499470.292 159 192.168.0.202 TCP_MISS/200 14206 GET http://213.139.228.232/Reports/Pages/Folder.aspx - PINNED/213.139.228.232 How can I connect this site transparently? Thanks Yusuf
