jQuery - Update a div on page without refreshing the page
<p>I'm trying to make some Post Application which has to show messages like the Mail in Mac OSX. </p>

<p>I wan't to have headers shown in a div on the left of another div. The 'other div' has to show the message according to what header is selected. </p>

<p>All in all, I want the script to show some postContent matching postHeader, without refreshing the page - but still it has to add an URL statement like: <code>post.php?id=1</code>. </p>

<p>Is this even possible and how would you do that? :) </p>
