This more of a comprehension question about FAL in TYPO3 6.x.
I understand I can create new storage locations, and that I am not forced to use /fileadmin/ anymore. As FAL links aren't stored directly in tt_content, I suppose it should be possible to define rewriting rules for FAL links.
E.g. "replace /fileadmin/ by /storage/". Or "for all pages in this branch, remove /fileadmin/ and prepend http://static.domain.com". Etc.
But - on an integrator level that doesn't involve heavy coding (like in https://github.com/beechit/fal_securedownload) - that's not how it works, or is it?
