Proxy Help Required
Hi all,

There is alot of technical guys and girls here, so I thought I would ask. Basically we use 1 proxy server to access the Ford website. Now we have brought Chrysler now, and they use a different proxy server. To enable us to connect to both, at the moment I use a programe called netswitcher with enable me to switch Proxy Server settings without typing it in the IE Browser settings. The problem with this, is when I use Netswitcher, I get disconnect from Email server and other programes we use on the network.

What I am asking is, does anybody know of a programe that can run local on a PC ( as we don't have control over the proxy servers ) where it will allow me to enter the information of the 2 different proxy servers.

I can get around the different IP address and Gateway via the ROUTE ADD command, but its these poxy proxy servers which is causing me a headache.

Any info would be gratefully received.

Best Regards

To be honest, its more of an infrastructure level issue - not something you could really solve without either changing the ford and chrysler proxies, or running one in your own office. A solution would be to run a program as another proxy, which first checks one proxy, and then goes to a backup proxy (i.e. the Chrysler one). Unfortunately the only one I know which does it will is Squid - which is a pain in the arse to setup, and only runs on *ix, as far as I know.

Thanks vari, but Firefox is not compatible with some Java Applits that we use for Kia and Mazda.

Thanks TAA, thats what I thought, but usually when I think like that, people sometimes say, why don't you get X programe.

If it's for the browser only, then you can configure a static "Proxy Auto Config" (pac) file that defines which proxy should be used according to some predefined logic.

It's a plain javascript file that you can point the browser to (supported by both mozilla based browsers and IE).

Example, let's say that:

- everything on your LAN in addresses 192.168.*.* should be accessed directly without any proxy.
- proxy.ford.net:8080 is used to access the ford.com sites
- proxy.myisp.com:8020 is used to access the rest of the websites

Create a file called myproxy.pac which contains the following code (unverified):


function FindProxyForURL(url, host){

if (isInNet(host, "192.168.0.0", "255.255.0.0"))
return "DIRECT";

if (dnsDomainIs(host, ".ford.com"))
return "PROXY proxy.ford.net:8080";

return "PROXY proxy.myisp.com:8020";
}


Put this file on your network somewhere and point the browsers to it from at the proxy configuration page.
I haven't checked this code so there might be errors in it and it can probably be made better but that's the general idea. You can find some more info here.

Hope it helps.
