FasterCachedResourceResolver is a URIResolver using a optimized search time algorithm.
For a given href, will try to search the exact path in classp-ath in the exact directory META-INF/cache.
The fact of using META-INF directory is optimized (special jvm directory).
The other fact of using an exact directory makes also decrease dramaticly time search.
Finally, we spend ten times less time in searching; moreover using the path of
searched resource resolve the probleme of name colision and this is also a good thing...
href = http://foo/bar/file.txt
search resource : /META-INF/cache/foo/bar/file.txt
