Proxy configuration

[Tinus Kotzé <s13596128@bach.sun.ac.za>]

I am running on a LAN behind a firewall that connects me to the
internet. For opera and mozilla I select Automatic Proxy Configration
with a spesific adress of http://www.xxx.xx.xx/zzzzz.pac
How can I make Debian to use this for autoconfiguration and even
futhermore, how can I let KDE recognize this configuration for
webbrowsing. My kde (2.2 and 3.0/1) just don't want to do this
automatically. Can anybody please help me. Here is file zzzzz.pac's
layout.

Regards
