Keyword Blocking
Keyword blocking allows the Webcache to prevent access to URLs
containing particular words. Keyword Blocking can be enabled when you
set up the Webcache for Manual Content Filtering or 3Com Web Site
Filtering. You may specify a list of up to 900 URL keywords to the
Webcache. Any request containing these keywords in the URL will trigger
content filtering. Keyword Blocking is applied as a system wide policy
regardless of individual category sets in the Filter Policy.
Keyword blocking searches for keywords in the URL and not the Web site
itself. Blocking the keyword
gun will block http://www.gun.com/ as well
as http://www.guncontrol.com/ but not http://www.weapons.com/ even
if it mentions guns in the text.
Setting Up Keyword
Blocking Lists
To set up Keyword Blocking lists using the Web interface:
1 Log in to the Web interface.
2 Click Content Filter on the Toolbar.
3 Select Webcache Filtering > Keyword Blocking > Setup Keywords in the
Navigation Tree.
4 Select Enable Keyword Blocking to deny access to URLs that contain the
specific keyword.
Editing the Keyword
Blocking List
To add a keyword to the Keyword Blocking List:
1 Log in to the Web interface.
2 Click Content Filter on the Toolbar.
3 Select Webcache Filtering > Keyword Blocking > Edit List in the
Navigation Tree.
4 Enter the keyword that you want to add to the Keyword Blocking List and
click Add . Repeat this for each keyword that you want to add.
You can enter a maximum of 900 entries into the Keyword Blocking List
on the Webcache. If you enter more that 500 entries, you will be
presented with an error message. If you want to enter more than 500
entries you must use the
Load List From File command that allows you to
load and manage 900 entries. If you load more that 900 entries, all
entries after the 900th will be discarded.
