That would solve this problem, but by forcing the use of a proxy, we get better control of the web traffic. It also allows us to use group policy to block access to setting the proxy for users not allowed to browse the web, without jumping through hoops required to setup authentication on the proxy server. We can't just block access to IE, because these users do need access to intranet applications. Currently there are only a couple of users that have laptops and access sites that have this problem the others are on desktops, and setting them to use the configuration script is a onetime deal. Even these users are a very small percentage probably only around 2% of all users. Setting up a transparent proxy with authentication to stop the users not allowed internet access would have an impact on the other 98% of users who work just fine with the auto detect settings. Of course if Sun just implemented an auto detect option in the Java Runtime Environment proxy settings, all my problems would just go away.

It was set to manual configuration the first time I ran the command, so it appears to not look at the current settings but looks at what is in the registry for the manual configuration whether or not it is currently enabled. > > In XP: > To Display Current Settings: > proxycfg -d > To Import from IE: > Proxycfg -u > To Manually Set: > Proxycfg -p myproxy:port "<local>;localsite1;localsite2;..." > > Looks like under my environment I will have to use the manual set options to possibly solve the issue, the main problem I have found is that Java doesn't seem to work correctly if the browser is configured for auto detect, it will work however, if the browser is set to use a specific configuration script, or a manually configured proxy. Both of these options however do require the user to change settings if they have a laptop and try to use it outside of our network. > Guess if this command fixes the problem I can look at writing a startup script to detect if they are on our local LAN or not and set it to direct or a manual proxy depending on the result, then push this script to clients with group policy. > > Thanks, > Dean Weimer > Network Administrator > Orscheln Management Co > > -----Original Message----- > From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] > Sent: Wednesday, April 15, 2009 7:32 AM > To: Phillip Pi > Cc: squid-users@xxxxxxxxxxxxxxx > Subject: Re: Using Squid as a proxy to change network devices' properties instead of web broswers'? > > Phillip Pi wrote: >> Hello. >> >> I got Squid v2.7 stable 6 installed and working in a Windows XP Pro.
