Yes. And it is me who wrote this based on the experience where the
problem was first seen. The problem was detected in a system using
cookies (%{Cookie} in the external_acl_type specification) and then all
hell broke loose when a new cookie was issued to the browser in certain
conditions, causing a new external_acl helper lookup in the middle of a
browsing session.

Maybe, but just maybe the problem also can be seen when the ttl expires.
I am not sure, but I want to rule this out before looking too deeply
after other causes.
