Hi, I wish to configure squid in such a way that The client should be able to authenticate proxy by Basic/Digest/NTLM. It should accept HTTP and HTTPS requests on different ports. I am confused about how to enable both simultaneously. I saw some examples using https_port but I got none working so...My Squid version is 2.6 stable 10 >From squid doc I got to understand that their are two ways of Client -> Proxy->Server connection 1) Client connects with Proxy at https port. Proxy tunnels the request to sever without modifying the messages, through the connect method. And client server exchange certificates. 2) Client connects to Proxy at https port. Proxy and client have exchnage of certifcates. And an ssl connection is established between the two. Now, Proxy modifies the request and establishes the connection between the Proxy and Server by exchange of certificates between the two. I would request any working - squid.conf - config lines, if possible. Thanks and Regards, KM
