Comment (by yawning):

 or/directory.c:directory_handle_command_get()
 {{{
   if ((header = http_get_header(headers, "Accept-Encoding: "))) {
     compression_methods_supported = parse_accept_encoding_header(header);
     tor_free(header);
   } else {
     compression_methods_supported = (1u << NO_METHOD);
     if (zlib_compressed_in_url)
       compression_methods_supported |= (1u << ZLIB_METHOD);
   }
 }}}

 That's at least one of the problems.  If `zlib_compressed_in_url` is set,
 the data to be transferred before `Accept-Encoding: ` is taken into
 account should be zlib compressed payload.
