     actually sends compressed data, it determines what type of
     content encoding the browser will accept ("gzip", "deflate" or
     none at all) and will return its output accordingly.  All
     browsers are supported since it's up to the browser to send the
     correct header saying that it accepts compressed web pages.
     If a browser doesn't support compressed pages this function returns
