but this is false, since RFC 2068 defines "deflate":

#deflate The "zlib" format defined in RFC 1950[31] in combination with
#        the "deflate" compression mechanism described in RFC 1951[29].

and hopefully HTTP/1.1 servers will support even on-the-fly compression
and HTTP/1.1 clients will use accept-encoding to allow compressed file
