title: How do I implement bread-crumb navigation similar to Facebook?
body: <p>I'm trying to make an Ajax Web Application that uses bread-crumbing to allow the use of the Back and Forward Buttons, but still have that slick ajax page movement.</p>
  
  <p>An excellent example is Facebook's image gallery.</p>
  
  <p>When you click 'Next' the URL changes to the respective URL but the entire page does not update. It's a really smooth interface and I'd like to mimic that.</p>
  
  <p>Anyone got a tutorial/write up on how this works?</p>
  
  <p>Thanks. </p>
