Hi Recently 'delete handler' was added in jackrabbit. This provides the ability to add handlers for handling webdav based 'delete' requests. See JCR-3884 <https://issues.apache.org/jira/browse/JCR-3884>containing details on this. Earlier this ability was just available for other webdav operations like to copy/move etc. but was missing for 'delete' .
Sling has written its own managers to keep track of these handlers. See [1] which has pre-existing handler managers like SlingCopyMoveManager. I have logged SLING-4825 <https://issues.apache.org/jira/browse/SLING-4825> for this. The intent of this jira issue is to add a delete handler manager so that the delete handler functionality can now be leveraged in Sling. I have implemented a proposed implementation for this. Please see [2]. Its exactly similar to how the existing handler managers function in sling.
