       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.
