Working with categories

Use the Policy Management > Filters > Edit Category Filter page to make changes to existing category filters.


	Important When you edit a category filter, the changes affect every policy that enforces the filter. Policies that enforce a category filter with the same name in another delegated administration role are not affected.

The filter name and description appear at the top of the page.

Click Rename to change the filter name.

Simply type in the Description field to change the filter description.

The number next to Policies using this filter shows how many policies currently use the selected filter. If the category filter is active, click View Policies for a list of policies that enforce the filter.

The bottom portion of the page shows a list of categories and the actions currently applied to each.

Select an entry in the Categories list to view category information or to change the action associated with the selected category.

Before making changes to the action applied to a category, use the details section (to the right of the Categories list) to review any special attributes associated with the category.

To list recategorized URLs assigned to the category, if any, click See custom URLs in this category. See Reclassifying specific URLs.

To list keywords assigned to the category, click See keywords in this category. See Keyword-based policy enforcement.

To list regular expressions used to define custom URLs or keywords for the category, click See regular expressions in this category.

Use the buttons to the right of the category list to change the action applied to the selected category. For more information about the available actions, see Actions.

Delegated administrators cannot change the action assigned to categories that have been locked by a Super Administrator.

Use the check boxes to the right of the Categories list to apply advanced actions to the selected category:

To change the way that keywords are used for assigning requests to the selected category, mark or clear Block keywords. Keyword-based policy enforcement

To determine whether users can access certain types of files from sites in the selected category, mark or clear Block file types. See Managing traffic based on file type.

If you have chosen to block file types, select one or more file types to block.

To apply the selected file type settings to all permitted categories in the filter, click Apply to All Categories.


	Warning With TRITON AP-WEB, applying file type blocking to all categories may have a serious performance impact. All files with an extension that does not match the blocked type are scanned to find their true file type, including text files, like HTML and CSS files.

To specify whether access to sites in the category is limited based on certain bandwidth thresholds, mark or clear Block with Bandwidth Optimizer. See Using Bandwidth Optimizer to manage bandwidth.

If you have chosen to block based on bandwidth, specify which threshold limits to use.

To apply the selected bandwidth settings to all permitted categories in the filter, click Apply to All Categories.

Repeat steps 1 through 3 to make changes to the actions applied to other categories.

After editing the filter, click OK to cache your changes and return to the Filters page. Changes are not implemented until you click Save and Deploy.

To activate a new category filter, add it to a policy and assign the policy to clients. See Web Protection Policies.
