Making urllib2 work with proxy urls

[Anand Pillai]

My company uses an automatic proxy configuration url of the form
http://server.company.com/department/proxy.pac .

I have made urllib2 work with normal proxies/firewalls, even the ones
requiring authentication, but I am stuck with this problem.

I tried getting the actual proxy server IP and configuring urllib2
with the normal way it works with proxies, but it has not worked
for me.

Any suggestions are welcome.

Thanks

The pac file is usually just a script with the config data for
browsers, it will return something like "PROXY
http-proxy.mydomain.com:80"

I very much doubt urllib2 can actually proces the .pac file.

You should be able to open that file and figure out what you need to
set the proxy variable to in urllib2 (or your ENVironment).

urllib just "automagically" works through proxies, not sure about
2....

A PAC file is a script that defines a JavaScript function:

function FindProxyForURL(url, host) {
// based on url & host:
// return "DIRECT" to use no proxy, or something like
// return "PROXY proxy.example.com:8080" to use that proxy
}

This function can get quite complex, so to use it automaticly, you might
need a JavaScript engine...
