checks all web pages for that word. For a phrase, the FortiGate
checks all web pages for any word in the phrase. For a phrase in
quotation marks, the FortiGate unit checks all web pages for the
entire phrase.

Select to enable the pattern.
URL filter
Allow or block access to specific URLs by adding them to the URL filter list. Add
patterns using text and regular expressions (or wildcard characters) to allow or
block URLs. The FortiGate unit allows or blocks web pages matching any
specified URLs or patterns and displays a replacement message instead.
Note: Enable Web filtering > Web URL Filter in a firewall Protection Profile to activate the
URL filter settings.
Note: URL blocking does not block access to other services that users can access with a
web browser. For example, URL blocking does not block access to
ftp://ftp.example.com. Instead, use firewall policies to deny FTP connections.
Viewing the URL filter list catalog
You can add multiple URL filter lists and then select the best URL filter list for each
protection profile.
