Overriding URL categorization

Updated: February 1, 2011

Applies To: Forefront Threat Management Gateway (TMG)

You can change the URL categorization of a URL or IP address by creating a URL category override. The following procedures describe how to create a URL category override for a specific array, or for all the arrays in an enterprise:

  • Adding a URL category override for an array

  • Adding a URL category override for the enterprise

Note

The following is true for both procedures:

  • Each URL must include a host name and a path, and may include a query string and escaped characters (such as “%20” to represent a space).

  • Do not include a protocol (such as HTTP://) with the URL.

  • Forefront TMG does not support the use of Internationalized Domain Name (IDN) URLs.

  • The URLs www.mycompany.com/homepage and www.mycompany/homepage/ are considered to be the same URL; the final closing slash does not affect URL categorization.

Note

Changing URL categorization on the enterprise level is a new feature in Forefront TMG 2010 SP1.

  1. In the Forefront TMG Management console, in the tree, click Web Access Policy.

  2. In the Tasks pane, click Configure URL Category Overrides.

  6. Click OK. The URL Categories Override dialog closes. Click OK again and then on the Apply Changes bar, click Apply.
