<FilesMatch ".(js|css)$"> vs <filesMatch "\.(js|css)$">
as far as i know the apache directives are case sensitive.
also the directive matches a "Perl Compatible Regular Expression", so you need the backslash to escape the dot.
i would not make the file extensions case insensitive unless you are actually serving uppercase or mixed case file names.
