Save last visited user page with Ajaxify anything

I have constructed the site on drupal with use ajax. All works correctly, simply remarkably, but I would like to make the following. I will explain on an example: Someone has visited my site and looks through it linearly, that is loads page one for another. But in what that the moment page loading has not occurred on what that to the reason (I use Popups API (Ajax Dialogs) which, at an error of loading of page, asks the user to refresh page and to find that is necessary to it. Agree, it is not absolutely pleasant...). I would like, that somehow it would be possible to keep page which the user has visited last, in cookies for example, and that at page refresh, it has appeared just on that page where it was last time. I about it have approximate representation, but here what variant the best - it would be desirable to consult.

I will be glad to any offers.

wbr, Xaber.
