Invalidation

Invalidation ensures that users see the latest versions of your assets without outdated content being served from cache.

Invalidation is the process of removing outdated cached versions of assets from the Content Delivery Network (CDN) to ensure updates are visible to users.

DAM invalidates automatically the old version of the asset when a new version is created. Users with Developer, Manager, Administrator or Owner User Roles can perform invalidations manually.

Steps to perform Invalidation

1. Go to DMO > Invalidation page

2. click on the + Add Invalidation form button.

3. Choose the Invalidation scope:

   1. Original - deletes the cache of individual assets. If you choose this option, please provide up to 5-10 urls in format /folder1/folder2/filename.xxx (Example: /campaigns/winter_sale/banner.jpg). The URLs can be separated with comma or a line break symbol. Do not include query string parameters at the end of the URL.

   2. All - deletes the entire cache of the project from the CDN and the resizing servers. Please pay notice that after invalidation the cache needs to rebuild again and the very first requests take more time for delivery.

When the Invalidation request is submitted, it appears in the Invalidation log. Both manual and automatic invalidations are logged there.

Details of the Invalidation request

Every request has the following parameters:

• Invalidation ID - the unique identifier of the request

• Scope - the scope of the request (original / all)

• Date - the datetime when the request has been submitted for execution. The value is in the local time zone.

• Status - the status of the request:

  • Received - the request is received

  • Preparing - the Invalidation server prepares the request for execution

  • Flushing Scaleflex servers - the cache of the resizing servers is in process of deletion

  • Flushing CDN servers - the cache of the CDN servers is in process of deletion

  • Done - the invalidation finished successfully

  • ERROR_CDN_NODE - error in the CDN invalidation

  • ERROR - general error in some of the invalidation steps

If you encounter ERROR or ERROR_CDN_NODE, retry or contact support.

• Invalidation path - if you click on "See links", you can inspect which URLs have been requested for invalidation (applicable for the invalidations with scope "original")

• Retry - you can retry the invalidation in case of need
