Using a PAC file to restrict access to Websites

If you want to control which websites can be accessed from one or more computers a PAC file solution can be used.

The PAC file is a fairly simple file containing information on which sites can or cant be accessed – depending on what your needs are. This means you can set up a solution where all websites can be accessed except from the ones in your PAC file or you can setup a solution where all websites are blocked except from the ones in the PAC file.

In Internet Explorer you then have to enable the “Use automatic configuration script” under Tools > Internet Options > Connections > LAN Setting and then point to the location of your PAC file. The PAC file can be placed both locally or on a webserver.

Example of a PAC file where only the sites *.google.com, *.facebook.com and *.msn.com can be accessed (Proxy.pac):

Example of a PAC file where the above sites are blocked and all other sites can be accessed.
