Proxy.pac Auto-Configuration Script
Posted: Sat Aug 16, 2008 1:32 am
Brain storming here... Auto-Configuration script - Proxy *.pac file configuration.
Here's the scenario: Speaking IE language here, one would typically go to Tools, Internet Options, Connections, LAN Settings and set an Auto-configuration URL for a proxy pac file. (Same applies to FireFox but navigation is a bit different).
In my particular case, the proxy pac URL is behind a firewall. So when you connect from HOME, it will seek out the URL and then time out within a reasonable period, and resort to DIRECT connect; because it can't find the autoconfig URL.
They NEED this proxy.pac file to connect to the Internet once inside our VPN.
The problem is: When a customer/user uses a Wireless Broadband Modem (aka aircard) to connect to the Internet, they are ont he "outside". The timeout that normally takes place within 30 seconds or so when on a Time Warner wired/wireless router connection. When on a wireless aircard, the timeout is like 4 minutes.
SO: I think I need a LOCAL pac file that will do the following (in laymans terms):
If my IP is that of my ISP's aircard THEN
RETURN: DIRECT
else
If my IP is that of our VPN THEN
RETURN: http://addressbehindmyfirewall/Proxy.pac
End if
Our internal proxy.pac file gets updated regularly so I cannot copy the contents locally.
Ok, enough babbling - thoughts from here?
Thanks in advance!
