Category Lookup

Category Lookup

Category Lookup Overview

Category Lookup allows you to check the Categories assigned to URLs in the lookup process and provides you with additional information regarding how it is processed. 

Category Definitions

The Category Definitions contains official definitions of what type of content a URL must contain to be included into each of the available Categories. Additionally, if you create a new category, it will also show up in Category Definitions in the WebAdmin. You can sort the definitions by name, number, or group. If you are looking for a category, you can search the list by keyword.  There are two views in this window: The Classic view which is like previous releases and the ‘Hierarchy View’.

Please see the Category Definitions documentation for more information.

Categories Mismatch Detected

This warning indicates that one or more servers returned different results than another. This may occur if changes have not been applied to a server or a server configuration was done improperly.


By default, the 'Details' column is disabled. When enabled, it displays the full results for a URL including multiple Policy Servers and each step in which the URL is processed. The information displayed includes the server, category assigned, the Processing Step, and the URL/Keyword that was applied.

User Agent

Use this field to specify the application that is performing the request for all Category Lookups. I For example, Firefox, Chrome, and Internet Explorer have their own User Agent.

User Agent Example

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36


Try All IP Addresses:

If this is checked, the 'Detail' column will display the different destination IP addresses, such as, one for IPv4 and another one for IPv6. It then sends all commands to the policy servers, gets results and merges them. If some lookup steps produce the same result for all IPs, it is shown only once. If some step results are different, they are merged in the list.

Show All Steps

The 'Show All Steps' checkbox option shows all policy processing steps for a request until processing stops. It will show all steps that were tried even if the step did not apply to the specified URL.

This window can also be accessed from the Actions dropdown in the 'Request Logs' window.
