[OpenLayers-Users] Bounding box after every pan

You could add a "move" event handler to the map. In that handler you can 
call  getextent. However, a pan or zoom will call a moveto on all 
layers. I dont know what effect that will have on a WFS layer - it may 
preempt you.

However, I would strongly suggest that you rethink that design a little. 
You will get better performance if you use WMS for displaying the layer 
and only use WFS for query/selection.
