Creating a content invalidation request

Using Media portal, you can create requests to invalidate content for caching or streaming resources on the Lumen CDN. In the request, you specify the information for the resources that should be refreshed. For caching resources, you specify the property and path; for streaming resources, you specify the streaming ID and path. Once you submit your request, you can check its status.

To create a content invalidation request:

  1. From the main menu, select Network Tools > Content Invalidation.
Content Invalidation
  1. From the Access Group list, select the access group with the resources you want to invalidate.
  1. Select a radio button in the Invalidation Type field:

    • To issue a GIMS (GET with an if-modified-since header) request on the next request (assuming that the resource being invalidated has a last-modified header), select the Normal radio button.

    • To trigger an unconditional revalidation on the next request (causing the resource to be reloaded), select the Force radio button.
  1. If you want the invalidation request to match URLs without looking at letter case, select the Ignore Case checkbox.
  1. If you want Media portal to email you when your invalidation request is complete, click the Notify when complete checkbox. (We recommend using this option if you're submitting only a few requests.)

Note: Media portal sends an email if the invalidation request isn't completed within 12 hours. If you receive an email in this situation, contact CDN Support.

  1. In the Caching Property or Streaming ID list, select the property or streaming ID with the resources you want to invalidate. (You can also start typing the property or ID to filter the list.)
  1. In the Path(s) field, type the path(s) to the resource on the origin server relative to the web root. You can specify a path as either a complete path (in an abspath style) or using one or more wildcard specifications. (For example, to invalidate http://cdn.mycompany.com/images/logo.jpg, select cdn.mycompany.com in the Caching Property or Streaming ID list, then type /images/logo.jpg into the Path(s) field.)
