Strategy People,

When I use the Layer.WFS, I often set a 'maxfeatures' parameter, to
limit the amount of data that is loaded at once. The result of this is
that when a user zooms in, I want the previous set of data to be

Ideally, of course, if the number of features returned was fewer than
$max_features, there would be no need to invalidate the previous dataset
when zooming in (only when zooming out).

The current BBOX strategy does not allow for this as an option of any

Is adding this type of support something that belongs in the BBOX
strategy, or somewhere else?
