<div>Hi Roald,</div>
<div>There are two things I want to know.</div>
<div>1. How to send WFS requests to server with openlayers? I know the way to load WFS layers when I initialize map, but after loading layers, I don't know how to request WFS with Spatial Operations in OpenLayers.</div>
<div> </div>
<div>2. I also want to know the way to display a WFS layer on my map that automatically requests the correct features within the BBOX of the viewport?</div>
<div> </div>
<div>Thanks in advance.</div>

Do you want to display a WFS layer on your map that automatically requests the correct features within the BBOX of the viewport or do you want to have control over what BBOX you send to the WFS server and send your WFS 'manually'?<br>
<br>Maybe it is good to have a look at some examples (type WFS in the search box): [1].<br><br>Regards, Roald<br><br>[1] <a href="http://www.openlayers.org/dev/examples/" target="_blank">http://www.openlayers.org/dev/examples/</a><br>
