New Approach to Cache-Busting Embedded Content in Drupal with ECA Module

Drupal developers have introduced a method to address caching issues for pages containing embedded personalized or authenticated content using the Events, Conditions, and Actions (ECA) module. While Drupal’s caching strategy is generally effective, situations involving embedded content from external sites may require cache adjustments to ensure proper functionality. The ECA Cache module allows users to modify cache settings for render arrays, specifically by setting the Max-Age cache header to zero. This is achieved using the "ECA Entity" event from the cache module. However, in a recent client project, it was discovered that this approach alone was insufficient. To fully disable caching, developers had to activate Drupal's internal page cache kill switch, which lacked an existing plugin solution. A custom plugin was created to address this need, with plans for potential inclusion in the ECA Cache module. For those seeking this functionality before its release, further details can be found in the related Drupal.org issue (3493008).
