Edge Security Acceleration:Purge all cache

Scenarios

• Large-scale update of website content

• Replacement or redeployment of an entire website

• Unknown cache pollution

Purge all cache

1. In the ESA console, choose Websites. In the Website column, click the target website.

2. In the left navigation pane, choose Caching > Purge Cache.

3. On the Purge Cache tab, configure the purge settings.

   • Type: Select Purge All Cache.

   • Purge Method: Select Mark as Expired or Delete.

     • Mark as Expired

       If the requested content is one of the resources that you submit to purge, the nearest POP checks the Last-Modified parameter of the resource on the origin server. If the parameter value is the same as that of the cached resource, the POP serves the cached resource. Otherwise, the cached resource is considered expired. In this case, the POP fetches the latest version from the origin server, delivers it to the client, and updates the cache with the new version.

     • Delete

       If the requested content is one of the resources that you submit to purge, the nearest POP fetches the latest version from the origin server, delivers it to the client, and updates the cache with the new version.

   

4. Click Submit.

5. View the purge progress.

   You can view the progress and details of a purge task on the Operation Records tab. The purge task is complete when the progress reaches 100%. The progress varies based on the number of objects that you want to purge.
