Hi Heiko,<div><br></div><div>How are you serving your WMS layers? Can't you just use tiling in OpenLayers and cache the tiles on the server (like GeoWebCache)? This should solve your resizing problems and your slow rendering...</div>

<br>
we have several WMS Layers some of which are expensive (in machine cycles) to render raster images. We do observe that each time the Browser Window is rezised or the user pans/zooms a WMS request is generated for every zoom/pan/resize level.<br>
<br>
Is there a possibility in OpenLayer to supress the rerendering or the newly generated WMS requests till the zoom/pan/resize comes to a halt for certain period of time ?<br>
<br>
The situation now could bust the server if someone has a nervous hand on the mouse ...<br>
<br>
Thanks and Regards<br>
Heiko<br>
