How can I load new content without reloading the page based on hashtags fragments?
<p>Imagine I'm on:</p>

<p><a href="http://example.com/" rel="nofollow">http://example.com/</a></p>

<p>I click in a link containing a hashbang <a href="http://en.wikipedia.org/wiki/Fragment_identifier" rel="nofollow">fragment identifier</a>, let's say:</p>

<p><a href="http://example.com/#!/login" rel="nofollow">http://example.com/#!/login</a></p>

<p>I would like it to show the login form without reloading the page. How is this done?</p>
