Configuring Web URL Filtering
Web URL Filtering allows you to block HTTP access to malicious websites based
on URL categories. You can allow or block an entire URL category to make
configuration simpler. You can also specify the website exceptions against the
URL category settings. For example, you can block the websites that Web URL
Filtering usually allows, or allow the websites that Web URL Filtering usually
blocks.
You can enable Web URL Filtering Alert to send email alerts to a specific email
address when web URL categories have any changes. See Configuring Email Alert
Settings, page 408.
Web URL Filtering only monitors and controls the website visits through the HTTP
port specified on the Web URL Filtering > Advanced Settings page.
