ajax and browser back button in wicket 6

[Steve Lowery]

I did a search in the user list and found several references of various
ways to solve the back button using ajax problem, but most were a few years
old.  I was wondering if wicket 6 does can do this out of the box now.  One
of the stated goals on the wicket site is that it will "Fully solve back
button problem".  Does this hold true for ajax requests or just plain http
requests (or both)?
