Was thinking I should give an example of a proxy auto configuration script:

pac.conf : 
/* proxy auto configuration file sample */

function FindProxyForURL(url, host)
{
        var proxy_no = "DIRECT";
        var proxy_yes = "PROXY proxy.domain.com:3128";

/* Generally matches internal hosts.  Ex: "https://hostname/"; */
        if (isPlainHostName(host)) return proxy_no;

/* Matches domain to not proxy */
        if (dnsDomainIs(host, "noproxydomain.com")) return proxy_no;

/* Local networks - allows skipping proxy for LAN servers */
        if (isInNet(host, "192.168.0.0", "255.255.0.0")) return proxy_no;       
     

        return proxy_yes;
}

You'd host that config on some internal web server and have your browsers 
configured to load the configuration script.  Then the client evaluates the 
host/IP and makes the decision to route via the proxy (proxy_yes) or not 
(proxy_no).  Keep in mind the configuration is top down and the first match 
will apply.  There are likely better and more complete examples online.  Just 
wanted to expand on my previous reply.

Dear all, I have a Squid server in non-transparent mode.

All my hosts go to Internet sites using this proxy in the correct way.

But now I need the following:

When my hosts want to go to the internal URL https://www.example.com, this 
request reaches Squid and it tells them to go to the internal IP from our 
backend web server .....Maybe a certain type of redirect.

Is this possible?

Special thanks!!!
