Web Site Blocking allows you to control which Web sites can be accessed 
through the Webcache. If you enable web site blocking, you can enter 
the domain names of Web sites that you want to either allow or deny 
access to. You can specify one of two blanket rules with exceptions; 
either “Deny access to all sites except...” the ones that you enter, or 
“Allow access to all sites except...” the ones that you enter. Web requests 
from client machines will then either be served or blocked by the 
Webcache, according to the rules that you have set up. A customizable, 
automatically generated Web page informs the end user that access to 
the Web site has been denied.
