Plain Ajax or Iframe and Ajax for CMS administration interface

[eluser]MeanStudios[/eluser]
If you want to use back button with AJAX then take a look at this jQuery plugin: http://www.asual.com/jquery/address/

I've just come across it on the "This Week in jQuery, Vol 6" blog post .

But ya, the only thing you need to use an iframe for in AJAX is if you are doing any kind of file uploading and that can all be taken care of with the jQuery Form Plugin.
