Hi All, I have a Redhat ES 5.3 with squid verion 3.1.1. I also use the NCSA authentication to control the user to access to the internet. This box has been enabled a simple auto script for redirect namely cace.pac on apache as the following: function FindProxyForURL(url, host) { if (dnsDomainIs( host,"xxxxxx.com")) return "DIRECT"; if (url.substring(0, 5) == "http:" || url.substring(0, 6) == "https:"|| url.substring(0, 4) == "ftp:") return "PROXY proxy.xxxx.com; DIRECT"; } When the user set directly to proxy.xxx.com at browser, squid asked for the user/password for only one timm of new session. However, if the user set at browser and point to auto redirect script, the brower aske to many pop up for entering user name and password for new session. For example, the squid ask to enter the password for google.com as 2 time, Another website is 3-4 time. Any help would be appreciated.
