Description

To be able to block URLs, a new Match Object Type called HTTP URL. When HTTP URL is selected, Match Object Content must be a full URL with the hostname and the URI separated by a "/"(i.e. youtube.com/SonicWall)

If there is no URI part in the URL, the URL must be terminated by a "/" (e.g. youtube.com/).

Match Type can be:

Partial
Exact
Suffix
Prefix
Regex.

This KB describes how to block URLs using the example of the following YouTube and Yahoo Groups URLs:

www.youtube.com/watch?v=btsGDHO_4lU
www.youtube.com/watch?v=ZlDqcmY_EV8
groups.yahoo.com/neo

NOTE: HTTP URL is only available for use in an App Rule policy with Policy Type selected as HTTP Client.
The following solution will not work if the traffic is over HTTPS unless DPI-SSL is enabled.
