Question : Large Proxy Exception List IE

I run a proxy server that limits when a person may or may not be online. I have a list of sites that I do not want the proxy server to use. I am using a group policy to push the proxy settings and use the Exception list for the sites that I do not want to use the proxy server. My problem is that my list is bigger then the allowed room in the exception window. Is there a way to make this area bigger or a way to script the exceptions so that I am able to have a larger list then I do now. The goal is to use the proxy server to block access for the users during certain times but let them use the internet for some sites at all times.

Microsoft Server 2003
All users XP Profesional or Windows 2000 Pro
 

Answer : Large Proxy Exception List IE

I would recomment using a proxy.pac script for this
Enable the the "Use Automaic configuration" option under your proxy settings at the client
and point it to a proxy.pac file on some of your webservers (most likely the proxyserver itself).
(e.g. http://proxyserver3.proxy.pac)

Some nice info on creating proxy.pac files, this netscape document is very usefull:

And this is some MS documentation on it:

Although it's javascript I believe so it should be Browser-independable.
