[web2py] Long Polling getting only the newly added records.

[David J.]

I am not sure how to go about long polling.

I need to know how to get only the most recently added items in the list;
My guess in solving this problem is to include a current row count and 
pass that as a parameter?
and then returning more rows that the current row count?

I am polling at 15 second intervals; so maybe a few rows are added in 
such time;

The idea is simply to avoid having to refresh the page.

I am not sure what is the most efficient way to handle it.

Any design ideas would be appreciated.


Thanks.
