You probably want to look at:

You can dynamically generate proxy.pac from a CGI script. Look at the source IP and customize appropriately.

http://www.squid-cache.org/mail-archive/squid-users/199708/0193.html

Just setup your web server to handle .pac or .dat requests as a CGI. In lighttpd you'd use cgi.assign and Apache would use AddHandler in your <Directory> config.

http://httpd.apache.org/docs/2.2/howto/cgi.html

Hope this helps.
