Manual Content
Filtering
Manual Content Filtering allows you to control which Web sites can be
accessed through the Webcache. If you enable Manual Content Filtering,
you must manually create a list of the domain names, IP addresses or IP
address ranges of Web sites to which you want to either allow or deny
access.
When you configure your Webcache to use Manual Filtering or the 3Com
Web Site Filtering service, the Websense Enterprise filtering commands
on the Webcache are disabled.
When a client computer attempts to access a Web site, the Webcache
applies the following rules in the order listed:
1
Web Client Blocking — If Web Client Blocking has been activated the
Webcache checks to see if the client is on the Web Client Blocking List.
Unauthorized clients will be blocked. See
“Web Client Blocking”
on
page 161
for more information.
2
Filter Exclusion — The Webcache checks to see if the client is on the Filter
Exclusion list. For authorized clients, further rules will be bypassed and
the clients granted access to the Website. See
“Filter Exclusions”
on
page 166
for more information.
3
Allow and Deny Lists — The Webcache checks to see if the Web site
being accessed has been expressly allowed or blocked (denied) by an
administrator. If the Web site is on the Allow List, the user is granted
access. If it is on the Deny List the access is blocked. If the site is not listed
then the Webcache looks at the next rule. See
“Setting Up Allow Lists
and Deny Lists”
on
page 169
for more information.
If a domain name appears in both the
Allow
and
Deny Lists
then it will be
filtered. To stop the site from being filtered, remove it from the
Deny List
.
4
Keyword Blocking — The Webcache checks all the entries in the Keyword
Blocking list against the domain name of the Web site for a partial match.
If a partial or complete match is found then the site is filtered, otherwise
the Webcache continues with the next rule. See
“Keyword Blocking”
on
page 174
for more information.
