URL categories in the same Access, Decryption, or Cisco Data Security Policy group and define
different actions to each category, the action of the higher included custom URL category takes effect.
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 to parse the
access logs. If the first four characters of the custom URL category include a space, Sawmill for cannot
properly parse the access log entry. Instead, only use supported characters in the first four characters if
you will use Sawmill for 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.
