DESCRIPTION
Used by Web servers to track usage and provide service based on ID.
A server that acts as an intermediary between a user and the Internet to provide security,
administrative control, and caching service. When a proxy server is located on the WAN it is
possible for LAN users to circumvent content filtering by pointing to this proxy server.
The Router can block Web sites with URLs that contain certain keywords in the domain name
or IP address. For example, if the keyword "bad" was enabled, all sites containing this
keyword in the domain name or IP address will be blocked, e.g., URL http://
www.website.com/bad.html would be blocked. Select this check box to enable this feature.
Type a keyword in this field. You may use any character (up to 64 characters). Wildcards are
not allowed. You can also enter a numerical IP address.
This list displays the keywords already added.
Click Add after you have typed a keyword.
Repeat this procedure to add other keywords. Up to 64 keywords are allowed.
When you try to access a web page containing a keyword, you will get a message telling you
that the content filter is blocking this request.
Highlight a keyword in the lower box and click Delete to remove it. The keyword disappears
from the text box after you click Apply.
Click this button to remove all of the listed keywords.
Click Apply to save your changes.
