Sites 

Enter one or more Site addresses for this custom category. You can enter 
multiple addresses separated by line breaks or commas. These addresses 
can be in any of the following formats:

IPv4 address, such as 10.1.1.0

IPv6 address, such as 2001:0db8::

IPv4 CIDR address, such as 10.1.1.0/24

IPv6 CIDR address, such as 2001:0db8::/32

Domain name, such as example.com

Hostname, such as crm.example.com

Partial hostname, such as .example.com; this will also match 
www.example.com

Regular expressions can be entered in the Advanced section, as 
described below.

It is possible to use the same address in multiple custom URL 
categories, but the order in which the categories are listed is relevant. If 
you include these categories in the same policy, and define different 
actions for each, the action defined for the category listed highest in the 
custom URL categories table will be the one applied.

(Optional) Click Sort URLs to sort all addresses in the Sites field.

Once you sort the addresses, you cannot retrieve their original order.

Advanced

You can use regular expressions to specify multiple addresses that match 
the patterns you enter.

The URL filtering engine compares URLs with addresses entered in 
the Sites field first. If the URL of a transaction matches an entry in 
the Sites field, it is not compared to any expression entered here.

See 

 for more information about using 

regular expressions.
