   The Accept-Encoding request-header field is similar to Accept, but
   restricts the content-codings (section 3.5) that are acceptable in
   the response.


       Accept-Encoding  = "Accept-Encoding" ":"
                      ( encoding *( "," encoding) )
       encoding         = ( codings *[ ";" "q" "=" qvalue ] )
       codings          = ( content-coding | "*" )

   Examples of its use are:

       Accept-Encoding: compress, gzip
       Accept-Encoding:
       Accept-Encoding: *
       Accept-Encoding: compress;q=0.5, gzip;q=1.0
       Accept-Encoding: gzip;q=1.0, identity; q=0.5, *;q=0
