Major Feature #26891
Implement basic static file caching as new caching framework backend
The "filebackend" of the caching framework can already write caches to the filesystem.
A new "urlbackend" shall be created that extends the existing filebackend. The identifier of a cache is in this case the URL.
This new mechanism shall write the file to accordant directories that can easily be used by a mod_rewrite rule without using TYPO3 - just plain Apache.
Available URL schemes are:
- RealURL (extension), e.g. host.com/some-section/page.html
- SimulateStaticDocument (core), e.g. host.com/page.123.0.html
- Plain, e.g. host.com/index.php?id=123
GET arguments should be considerred (after optimization, e.g. sorting the arguments alphabetically)
