As a result of the thread in
When filenames in the resource directory contain dots, and the farFuturecaching is set to true, the files cannot be found.
(for example jquery-1.7.1.js, core.module.js or jsscript.min.js)
The regular expression in /modules/cache/virtualURIMapping/tildeCacheRessources/fromURI
doesn't seem to handle occurences of dots in the filename itself.
(not all dots get replaced by a tilde?)
