Purge alternate response pages

When you want to purge a Cloudlet's alternate response pages, use the Enhanced Content Control Utility (ECCU). The ECCU lets you specify how cached objects are refreshed.

To purge your alternate response pages:

  • Set up an ECCU file containing the refresh instructions for the alternate response page.
  • Upload the ECCU file using one of the following methods:
    • the Enhanced Content Control Utility (ECCU) section of Content Control Utility application, which is available from Control Center.
    • the ECCU Publisher web service.

📘

For detailed information about the ECCU, see the Content Control Interfaces guide.

Set up an ECCU file

To purge your Cloudlet's alternate response page, you need to send a request with the following query string parameter: aka_static_purge.

In order for the ECCU to process that request, you need to set up an ECCU file for a query string purge where:

  • the value of the aka_static_purge query string parameter is true.
  • the URL to purge is either
    • the client URL sent in the request appended with the aka_static_purge query string parameter, or
    • the path to the alternate response, as defined in the Cloudlet behavior, appended with the aka_static_purge query string parameter.

For example: /path/alternateresponse.html?aka_static_purge=true.

Submit an ECCU request to purge branded pages

In Control Center, use ECCU to submit a request to purge branded pages.

You also have the option of using the ECCU Publisher web service.

  1. Go to > CDN > Purge cache. The Fast Purge application opens. Under Purge content by, select Directory and Extensions (Advanced), then click Next.

  2. Click the Refresh by Directory & File Extension link to view the ECCU page.

  3. Select the Digital Property Name(s) and, optionally, give this request a name to identify it in the future.

  4. Choose the refresh method:

    • Refresh all files in a directory

    • Refresh by directory and extension

    • Upload an ECCU file containing the refresh instructions.

  5. When you're ready, click the Next button to go to a confirmation page on which you can review your submission before finalizing it.

  6. On the confirmation page, review your data and when ready, click Submit. The metadata you see on the confirmation page is the ECCU file.

    The successful submission takes you to the Request Submitted page, where you should note the displayed Request ID that can be used for tracking and problem solving. If you want, click Refresh Content to return to the ECCU main page.
