Automatically detecting proxy settings

Having gotten sufficiently annoyed at the need to maintain two Mozilla
Firebird profiles just because I use a proxy in school and none at
home, I decided to look up the “Automatically detect proxy
configuration” option. After some digging around, this is the answer I found:

This goes into my /etc/laptop-net/profiles/school/files.d/var/www/proxy.js:

function FindProxyForURL(url,host)
{ if(isPlainHostName(host)||
    isInNet(host,"","")) return "DIRECT";
      else return "PROXY; DIRECT";

and this goes into my /etc/laptop-net/profiles/home/files.d/var/www/proxy.js:

function FindProxyForURL(url,host)
  return "DIRECT";

I deleted the other profile and changed my settings to automatically
detect the proxy configuration from file:///var/www/proxy.js .
Tada! No more worries. It just works.

    I guess you must be using a Linux system. How would I accomplish this on my windows system?

    Oh. Umm. You would probably switch to Linux. Sorry about that…

    No problem. Thanks for the response.
