The pager kicks ass, as it handles huge amount of data, using the

Everything works like a charm. Except... when the user clicks the
evil back button.
There, two things happen: first, the objects shown on the screen
are not the objects where actions will apply if you choose an
action on a displayed object (the same problem descibred here -
<http://groups.google.com/group/wotips/browse_thread/thread/
7fd37a82e5175537/17cef74b566fadd7#17cef74b566fadd7>). Second, if
you click on any link in the Pager (the Pager looks like "1 2 ...
56 57 58 59 ... 567 568"), the page where you'll end does not match
the link you clicked, because the link targets have changed.
The problem is that the Pager is a stateful component, and
everytime you change the page, the same components are reused
(return null). So, when you click "back", what you see is NOT what
you get.
Now... how do I solve this (in an elegant way, of course)? I
think the best solution is, somehow, keeping the state (or part of
it) of the component for all the pages. That way, when the user
backtracks, and clicks on something in the pager, I would be able
to go to the right state, and work from there.
Is this a situation that won't be resolved by response
().disableClientCaching()?
