Can I retrieve user's PAC file (Proxy Auto Config)?

Question

Is it possible?

Currently I'm trying per domain to get what proxy the system designates to it, this way:

Uri website = new Uri("http://google.com");
System.Net.IWebProxy defaultproxy = System.Net.WebRequest.GetSystemWebProxy();
Uri proxy = defaultproxy.GetProxy(website); 

This way I know what proxy the system gives me to google.com. But is it possible to get the whole pac file (javascript)?

Well, I'm not sure if it's best practice, but what I've managed so far is reading it using regedit. The relevant key is located here:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\AutoConfigURL

Hope it helps someone.
