Local proxy that supports upstream .pac files?

dive · 08-29-2013, 04:46 AM

I'd like to set up a proxy either local or on LAN server that has the ability to process an upstream .pac file and then send either the proxy address or the direct URL back to a browser.

I want to do this because Midori doesn't yet support .pac files directly, so I need some sort of middle-man solution.

I've looked at a few proxies like privoxy, tinyproxy, 3proxy, haproxy, but none of these support such a mthod either.

Has anyone ever set up something like this?

what is an upstream pac file? A pac file will come from a web server or a local disk, "upstream" doesn't figure in any of that The point is that it defines which "upstream" route to take. If you can get a pac file from some out-of-band mechanism, then why can't you just convert that file into config appropriate to your proxy of choice?

It's the converting into something useful that is giving me problems. I tried running a local webserver and using the pac as a normal javascript source but I never managed to get it to work.

a javascript source? What do you mean? Are you saying you're trying to *serve* the pac from a proxy now? It's probably worth you taking a step back and fully explaining what you're trying to achieve here, in simpler terms that are universally recognised.

Well a pac file is simply javascript that works out whether to connect direct or which proxy to use. What I tried to do was use that in a simple html page, as a javascript source. But it would probably need to be extended somewhat. I guess I would need to actually use the proxy url variable as a redirect and send the browser there or something.

Would just be easier if Midori supported pac files directly the same as other browsers do...

The only way I ever got it to work is using a internet connection sharing way. Then you don't put the pac in browser on client but upstream you put it there and share the connection downstream. I used to use Analogx on windows but ICS would work. I keep forgetting how to do this in linux.
