Long Polling don't works;

longpolling.js

function getContent( timestamp )
{
    var queryString = {"timestamp" : timestamp};

    $.ajax({
            type: "GET",
            url: '/php-long-polling-master/server/server.php',
            data: queryString, 
            sucess: function ( data ) {
            var obj = jQuery.parseJSON( data )[0];
            $( '#response' ).html( obj.content );       
            // reconnect with other timestamp from **server.php**
            getContent( obj.timestamp );
            }
    });
}


$( document ).ready ( function ()
{
    getContent();
});

server.php

<?php
require 'pdo.php';
set_time_limit(0);
while ( true )
{
    $requestedTimestamp = isset ( $_GET [ 'timestamp' ] ) ? (int)$_GET [ 'timestamp' ] : time();

    clearstatcache();

    $stmt = $pdo->prepare( "SELECT * FROM publication WHERE publication_time >= :requestedTimestamp" );

    $stmt->bindParam( ':requestedTimestamp', $requestedTimestamp );
    $stmt->execute();
    $rows = $stmt->fetchAll( PDO::FETCH_ASSOC );

    if ( count( $rows ) > 0 )
    {
        $json = json_encode( $rows );

        var_dump($rows);

        echo $json;
        break;


} else  {
    sleep( 2 );
    continue;
    }

}
?>

The problems:

1. longpolling.js don't have a timestamp, the log shows: get /directory/directory/server.php instead server.php?timestamp=TimeInMilisseconds

2. If don't have a timestamp, the server.php never will show results :|
