Back Button in RIA (Rich Internet Applications)

There is an inherent problem with the technologies that herald the advance of the internet from static text to "rich" applications (applications built using AJAX, Flash, Silverlight, etc) - they all "break" the back button.

No longer can a user naturally go back to the previous page (or state) unless RIA applications do a lot of work to enable this seemingly simple interaction.

I just wrote an article on codeproject that describes one way of getting this done, using the YUI JavaScript library.
