I set up URL keyword blocking, but I can still access a website that should be 
blocked.

Make sure that you select the Enable URL Keyword Blocking check box in the Content 
Filtering screen. Make sure that the keywords that you type are listed in the Keyword List. 
If a keyword that is listed in the Keyword List is not blocked when it is found in a URL, 
customize the keyword blocking using commands. See the Customizing Keyword Blocking 
URL Checking section in the Content Filter chapter.
