Hi all; I have a question about upstream proxy. I have blue coat proxy server and squid proxy server. We have 2 sites. I install squid proxy on my ubuntu and set parent server blue coat. cache_peer 192.168.x.x parent 8080 0 no-query default When the requests send to blue coat , blue coat doesn't authenticate users. When I edit squid.conf file and enter the cache_peer 192.168.x.x parent 8080 0 no-query default proxy-only login::, it works but only one user authenticate and all users are using this username and password. I want all users authenticate their own user name and password at bluecoat. How can i solve this problem?
