If your Ajax code is reloading the whole page every time anything changes, that's some awful code. I have seen such designs in the wild, but that's just because whoever wrote the script was a lousy developer. It's not supposed to be that way.

Here's how Ajax works: A whole page is downloaded once from the server, then the page's Ajax functions start running — and then when part of the page needs to be updated, the Ajax toolkit only has to reload that specific data and render it on the page.
