remember previous settings with page loads

I would like datatables to go to the state it was in the last time I had the page open. The parameters I'm interested in are Page, Sort Column, Sort Direction, and Previous Search Criteria.

I see that I can use fnPageChange() to go to the page. The others I have not figured out yet.

Also, I see that there is a function called fnSettings(), Is this the function I need to call to get the Sort, Search, and Page info that I need? I looked at the output of fnSettings() and I'm not real sure which values I should grab.

Thanks,
Jack
