Load page with AJAX

If you see Twitter following and followers users pages you can see this thing:

there's two tabs called "Following" and "Following" like this: [ Following | Followers ]

If you click Following, the page loads the following users page, if you click Followers the page loads the followers开发者_Go百科 users page.

When you click Following the URL become http://example.org/#!/following and when you click Followers the URL become http://example.org/#!/followers.

I want something like this, how can I implement it?

Thanks!

There are many plugins for jQuery that implement this, and I figure also for other frameworks.
