Using ECCU

How to use the Enhanced Content Control Utility (ECCU) to specify the refreshing of cached objects.

Before you begin

You’ll need to have access to Control Center. If you don’t have access to this Content Control Utility, contact your account representative.

Familiarize yourself with how this tool works, as discussed in subsequent sections. The specific kind of path and extension formulations may be new to many.

Before you upload ECCU files, you’ll need to be familiar with Digital Properties and with the ECCU file structure and options.

How to

  1. Log in to Control Center at
  2. From the Control Center menu, choose Purge Cache in the CDN section.
    The ECCU landing page shows all of the current ECCU requests listed in sequence by request ID, the name given to the request, the property associated with the request, the date the request was submitted, and the request’s status (pending, succeeded, or failed).
    Use filter to quickly find a request by name, request ID, property or status.
    For definitions of the data you see on this page, see About ECCU Data Fields. For information on the Property and ECCU file structure, see About Digital Properties.
  3. Click New Request to open the Create New ECCU Request modal.
  4. In the Request Name field, give the request a name, then select at least one property. You can select up to 20 properties per request.
  5. Enter email addresses of users or administrators who you want to receive notifications when the content is refreshed.
  6. Choose how to refresh your files:
    • You can specify a directory to refresh all files within (including subdirectories). The path must start with a "/". Regular expressions and special characters are not permitted. Specifying "/" by itself will refresh all the content for the selected Digital Properties. For example, /store/images.
    • You can select an ECCU file to upload that determines which files to refresh.
  7. You have the option to only refresh files with specific extensions. Enter the file extensions without the preceding dot. For example gif, html, and jpg. Regular expressions and special characters are not permitted.
  8. When you’re ready, click Next to preview your request.
  9. Review your request before finalizing it. The metadata you see on this page is the ECCU file.
  10. Click Next. Review the details of the purge request and click Submit when you are ready. The ECCU Request Confirmation page appears. It may take up to 30-40 minutes for the refresh request to complete.
    Attention: If you refresh large numbers of files at the same time, the origin may experience an increased load as new files are retrieved.
    The metadata that was submitted appears at the top of the page and the request IDs that have been submitted for each property associated with the request are listed at the bottom.
    Note: All failed requests are listed on this page as well.
  11. Note the Request IDs that appear as they can be used for tracking and problem solving.
  12. Click OK to return to the ECCU landing page.
