Anonymous users are allowed to post comments on your site and page caching is enabled. An anonymous user posts a comment but does not see it because the same cached version of the page is displayed before and after commenting.
Content refresh to the rescue. If a new comment is posted and published the cache entry of the content will be deleted and the user immediately sees the posted comment.
Content Refresh provides cache clearing functionality for various content related actions provided page caching is enabled and the minimum lifetime is greater that 0.
- The page cache for a page is cleared when a comment is added, edited or deleted.
