        URL encode/decode This implementation helps addressing two things:
        • As Apache's mod_proxy unfortunately (and almost utterly incomprehensibly) unescapes URLs before passing them on to the backend, you can use this method to use an alternative character (e.g. "!") rather than "%" as escape character.
        • Using this method, you can spare catching UnsupportedEncodingExceptions, that are never thrown or you'd be in much bigger trouble anyway. This method always uses utf-8 encoding.
