Hi Scott,
thank you for your reply
I following your suggestion to read the documentation, in particular this paragraph: "servlet-lifecycle-issues" https://sling.apache.org/documentation/the-sling-engine/servlets.html#servlet-lifecycle-issues
And to me seems that once a servlet is instantiated, it's not possible to stop it.
Because the requirement I have, i thinking if there is a way to check the progress of the Servlet?
Or if could be a useful way try to instantiate threads for each request and manage their live-cycle?
