Hi all: In testing we've noticed that zooming with a mouse wheel seems to 
generate lots of requests
at various resolutions on the way to the final zoom level. So, a wheel up 
generates server requests
at intermediate levels, most of which won't be displayed. Someone sitting there 
rolling their wheel up 
and down can hammer a server.  Short of disabling that control are there good 
ways to avoid this? 
Perhaps by only asking for data once there's been no activity on the wheel 
within a certain period.

Steve
