Thanks for the post, it’s a very interesting way to do it. We are ‘still’ in the traditional way of configuring the proxy using the pac script manually.
The biggest issue is that dozens of apps just don’t understand pac files:
– zypper (actually it’s aria2c and wget) for example.

Maybe you can help me ‘market’ libproxy 🙂

Then you can have even more fun with your new proxy settings.
