how to force a machine to go through proxy when it as an exception not to go

  • 772

I'm in a private domain where the client machines need a proxy server to access the internet. All the machines have an exception where every request to servers in my domain don't need to go through the proxy: don't use proxy to: .mydomain.com, 171.11.0.0/16 and so on...

Well, I now have a machine with an external IP, but I want my clients to access the machine using the dns name: www.mydomain.com.

However, since they need a proxy to go to the internet, but the browser has an exception not to go through proxy when using the domain, they never reach the machine and the connection times out.

My DNS server (bind) has the www machine with the external IP. If I use directly the IP address, it goes to a "under construction" page, because the server outside is configured with a named virtual server and I don't have access to it.

How can I solve this problem? how can I force the machines to go through the proxy even if they are configured not to go ?

if i remove the exception, all the other requests to servers inside will not work...

Cheers

    I'm very confused as to what is currently happening and what you mean by "an exception"

    However an obvious way to address the problem is to use a proxy auto-config script on the browsers:

    function FindProxyForURL(url, host)
{
   if (dnsDomainIs(host, ".mydomain.com"))
         return "DIRECT";
   else 
         return "PROXY yourproxy.mydomain.com:3129";
}

    (for preference you would serve this up from an internal webserver or put it on a shared drive so you can easily deploy updates).
