Köszi, már emlékszem. :)
Erre gondoltok:
https://en.wikipedia.org/wiki/Web_Proxy_Auto-Discovery_Protocol
https://en.wikipedia.org/wiki/Proxy_auto-config

Pl.:
http://wpad.example.com/wpad.dat

function FindProxyForURL(url, host) {
// our local URLs from the domains below example.com don't need a proxy:
if (shExpMatch(host, "*.example.com"))
{
return "DIRECT";
}

// URLs within this network are accessed through
// port 8080 on fastproxy.example.com:
if (isInNet(host, "10.0.0.0", "255.255.248.0"))
{
return "PROXY fastproxy.example.com:8080";
}

// All other requests go through port 8080 of proxy.example.com.
// should that fail to respond, go directly to the WWW:
return "PROXY proxy.example.com:8080; DIRECT";
}

# vagy pl.:

function FindProxyForURL(url, host)
{
return "PROXY proxy.example.com:8080; DIRECT";
}
