Enhanced CCU Request Format

This section describes the format of the Enhanced CCU request file and the metadata tags that can be used to define a refresh, or revalidate, request.

You can submit an Enhanced CCU request file to the edge network through ECCU file upload using the Enhanced Content Control Utility (ECCU) Web interface on the management center, or through the ECCU Publisher web service. The ECCU structure is also used directly with the ECCU Web interface, but requests made using the GUI are limited to path and extension matches. You can also view the resulting ECCU data in that interface.

Note: For a discussion of best practices—when to use this interface or a different content control interface, the advantages, disadvantages, and limitations of each, see Best Practices Considerations: Which Interface to Use, and Limitations.
