//$cn = str_replace(".","",$_SERVER['REMOTE_ADDR']);
//$finalcookie = "coki/".$cn.".txt";
$finalcookie = tempnam("/tmp", "CURLCOOKIE");

$url="http://www.ypox.com";
$login="$url/content/login.html";
$signup="$url/content/signup.action";

$agent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0";          

    $ch = curl_init();          
    curl_setopt($ch, CURLOPT_URL, $login);          
    curl_setopt($ch, CURLOPT_COOKIEJAR, $finalcookie);        
    curl_setopt($ch,CURLOPT_ENCODING,"gzip,deflate");

You could use verbose output to compare what curl is sending compared to what you expect to be sent. Maybe the cookies aren't being sent. Open a file write stream $fp and let curl print to that file a full text of what it's sending and receiving.

/* in your setup */
$fp = fopen ( 'somefile.txt', 'w' );
/* then later in your code, only once in first group */
curl_setopt ( $ch, CURLOPT_VERBOSE, true );
curl_setopt ( $ch, CURLOPT_STDERR, $fp );
