Oh my, I hope none of your customers or bosses gets wind of this comment...

The only plausible way to do this is actually the only accurate way to do

It is simple, keep the "bookmark" information at the tail ends of the
dataset you are presenting. If they say give me the next 20 rows the
database will take the bookmark data and walk 20 more rows from there. This
amounts to a little bit of "state" being embedded in your HTML but it works
just fine to do it that way.

The way I am suggesting it to be done gives the benefit of it being an
efficient operation for the server to perform and it delivers accurate
results to the client every time.

What more can you ask for?
