In addition, companies with large networks might need to configure more than one proxy server and
let users choose between them, based on transient conditions. By using .pac files, an administrator
can author a single script file that determines which of numerous proxies to use for all client
computers throughout the enterprise.
The following are some examples of how you might use a PAC file:
–
Choosing a proxy at random from a list for load balancing.
–
Rotating proxies by time of day or day of the week to accommodate a server maintenance
schedule.
–
Specifying a backup proxy server to use in case the primary proxy fails.
–
Specifying the nearest proxy for roaming users, based on the local subnet.
You can use a text editor to create a proxy auto-configuration (.pac) file for your browser. A .pac file
is a JavaScript file that contains logic that specifies one or more proxy servers to be used, depending
on the contents of the URL. Use the PAC URL field to specify the URL from which to retrieve the
.pac file. Then the browser uses the .pac file to determine the proxy settings. For details about .pac
files, see the following Microsoft Knowledge Base article:
