FWIW: what we do in MapFish is send the x,y position on each click to the server, have the server do the intersection work and send a GeoJSON representation of the matching features. Yes, this is one Ajax request per click, but performance is good enough in general. -- Eric _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
