jquery requests
<p>I have this jquery code</p>

<pre><code>$.post('data.php'{"request":"data_"+$(this).attr("data")},function(data){
  $("div").text(data);
});
</code></pre>

<p>But if somebody else can call my website like this</p>

<pre><code>$.ajax({
    url: 'http://www.website.com/data.php',
    data: { request: "data_1" },
    success: function(data) {
   alert(data);
    }
</code></pre>

<p>He can easily get mine data.
How prevent this?</p>
