On a BIG-IP® system without a URL database, if you want to control traffic based on the type of URL being requested, and you have many URLs to consider, you should configure user-defined URL categories and user-defined URL filters. This approach provides good performance, ease-of-use, and the ability to use the URL Category and the URL Filter Assign agents in a per-request policy.
If you have only a few URLs that you want to treat differently, you can probably skip creating user-defined URL categories and filters and use a simple URL Branching agent in a per-request policy. In this case, you specify the URLs that you want to match directly in the URL Branching agent.
To configure user-defined URL categories and URL filters, complete these tasks.
