I don't know about the ajax crawling answer, but I did that in one application to make the back/forward buttons and linking work with AJAX content. It was a major PITA because you basically have to implement URL routing both client and server side.

Can you explain a bit more about your circumstances so that I can understand why you needed to interpret URLs and anchors on the server and the client? The libraries I have used (jQTouch and Sammy) serve one single page and the client interprets the anchor. Thus, there is no need to implement URL routing on the server since you simply serve the application and let it route the URL. When you change states on the client, instead of changing state and then changing the anchor, you change the anchor and that triggers an event which causes the client to interpret the URL and change its own state. Thus, there is only one piece of code, ever, that handles routing.

  In my case I needed to be able to degrade gracefully when Javascript wasn't available, which meant I had to be able to do it server side as well. If you don't have to support that use case its definitely a lot easier.

    THAT is a very good explanation, thanks! p.s. If this happens to me, I expect I will extend my experimental Javascript view-controller framework so that it runs inside node.js. That way I could serve exactly the same content whether I was running in the browser or in node and I wouldn't need two sets of view logic.

      Yes! I haven't gotten too excited about the whole "run the same code on the server and the client" aspect of Node (mind you I've been very excited about other aspects of it, its my new favorite framework/whatever-it-is), but this is one application where I really think that could be beneficial.

Thanks for your GO game link, learned about "fun" alternatives for the game I didn't know before. I'll try them next time I play, thanks!
