The Web Security appliance ships with many predefined URL categories by default, such as
Web-based Email and more. However, you can also create user defined custom URL
categories that specify specific host names and IP addresses. You might want to create custom
URL categories for internal sites or a group of external sites you know you can trust.

Note — The Web Security appliance uses the first four characters of custom URL category
names preceded by “c_” in the access logs. Consider the custom URL category name if you
use Sawmill for IronPort to parse the access logs. If the first four characters of the custom URL
category include a space, Sawmill for IronPort cannot properly parse the access log entry.
Instead, only use supported characters in the first four characters if you will use Sawmill for
IronPort to parse the access logs. If you want to include the full name of a custom URL
category in the access logs, add the %XF format specifier to the access logs. For more
information on how to do this, see “Custom Formatting in Access Logs and W3C Logs” on
page 450.

It is possible to create multiple custom URL categories and include the same URL in each
category. The order of the custom URL categories matters. Categories listed higher in the list
take priority over categories listed lower. When you include these custom URL categories in
the same Access, Decryption, or IronPort Data Security Policy group and define different
actions to each category, the action of the higher included custom URL category takes effect.
