Hi Bertrand,

RSL stands for runtime shared library. Portions of the Flex SDK are
compiled into .SWZ files that are(were) signed by Adobe. This would yield
two benefits, 1.) security and 2.) Flash Player RSL caching at a global
level (all domains), meaning all sites using a specific version of the Flex
SDK can be cached only once by a user. Because Adobe will no longer sign
Apache Flex RSLs we lose #2. Having Apache host RSLs would help us to
resolve #1 as Adobe will no longer host our RSLs. I hope that's clear and
that I've gotten that all correct, someone correct me if I'm wrong here
