Hi, i am writing a program that allows me to chat at a website i have an account at. I made the following program which works, but i have to login first, then monitor the traffic and duplicate that.

use WWW::Mechanize;
$password = "******";
$url = "https://www.chess.com/login";
my $mech = WWW::Mechanize->new();
$cookie_jar = HTTP::Cookies->new( );
$mech->cookie_jar( $cookie_jar );
$mech->get($url);
$mech->submit_form(
  form_id   => "LoginForm",
  fields    => { username=>"tenny", password  => $password },
);
die "hmmm" unless ($mech->success);    
$mech->get("http://live.chess.comlive?v=2014060601");
$req = HTTP::Request->new(POST => 'http://live.chess.com/cometd/');
$req->header(Host=> 'live.chess.com',
User-Agent=> 'Mozilla/5.0 (Windows NT 5.1; rv=>14.0) Gecko/20100101 Fi

    $req->content('{"channel":"/service/user","data":{"txt":"very bad 
+connection today","id":"R1","sid":"cserv","tid":"Chat"},"id":"2730","
+clientId":"o"}');

$res = $mech->request($req);
 if ($res->is_success) {
 print $res->content;
  }
 else {
 print $res->status_line, "\n";
  }

Of course i dont want to do it like this so i try to get the required information the official way and by monitoring the http traffic i can see the following information being send to http://live.chess.com/cometd/handshake: 

('{"clientFeatures":{"protocolversion":"1.03","clienttype":"LC4Full","
+clientname":"LC4Full v2014060601; Firefox/14; Windows","multiplegames
+":true,"examineboard":true},"serviceChannels":["/service/user","/serv
+ice/tournament","/service/game","/service/examine"],"version":"1.0","
+minimumVersion":"1.0","channel":"/meta/handshake","supportedConnectio
+nTypes":["long-polling","ssl-long-polling","callback-polling"],"advic
+e":{"timeout":60000,"interval":0},"id":"1","ext":{"ack":true,"timesyn
+c":{"tc":1402752382334,"l":0,"o":0}}}')

After this you get an id nr and some more information needed. Now i tried duplicating this info but i get an error:

[{"id":"1","error":"403::Handshake denied","successful":false,"advice"
+:{"reconnect":"none"},"channel":"/meta/handshake","ext":{"timesync
{"ts":1402994052362,"t
c":1402752382334,"a":-241670028,"p":4},"hfdetails":"authentication-fai
+led"}}]

What i wanted to ask if someone can tell me what information is being provided here,and more importantly how does the browser know what info to provide? I hope you can understand my question.Ty
