Hello,<br>
<br>
If you run a WFS GetCapabilities request on your server, it should
tell which filters it supports, see :<br>
<a class="moz-txt-link-freetext" href="http://mapserver.org/ogc/filter_encoding.html#server-side">http://mapserver.org/ogc/filter_encoding.html#server-side</a><br>
<br>
Someone correct me if I'm wrong, but I think MapServer needs to be
compiled with GEOS in order to do intersect filters.<br>

I've dome some reading but not sure exactly what's supported. I
have used both INTERSECT and INTERSECTS, both return the same
error. Should I skip these and go with BBOX? If so, I assume I
would need to get rid of the lowerCorner/upperCorner items and
just list the coordinates separated by commas. Or could there be
a problem with the PropertyName = SHAPE? I couldn't find doc on
what this value should be. My data are either shapefiles or
postgis layers.<br>
<br>
The POST request is:<br>
