         * Compressed responses can use Content-Encoding and/or Transfer-Encoding.
         * The semantics differ slightly, but it is suffice to say that most user
         * agents don't advertise their Transfer-Encoding support.
         * So for now we only support the Content-Encoding mechanism.
         * Some other notes:
         *  - Some clients implement 'deflate' incorrectly. Hence we only support 'gzip',
         *    despite it having slightly more overhead.
         *  - We don't use Undertow's built-in compression support because we've
         *    pre-calculated the compressed response and expect to serve it up
         *    repeatedly, instead of calculating it on-the-fly for every request.
