Hey!
I have set up Mapserver to serve data from my PostGIS database through a
WFS. I am using OpenLayers as a client. When I load my test page for the
first time OpenLayers sends the following request:
<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; service="WFS"
version="1.0.0" xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd";>
<wfs:Query typeName="omega">
<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc";>
<ogc:BBOX>
<ogc:PropertyName>the_geom</ogc:PropertyName>
<gml:Box xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326">
<gml:coordinates decimal="." cs="," ts=" ">135.45,-47.425
157.95,-36.175</gml:coordinates>
</gml:Box>
</ogc:BBOX>
</ogc:Filter>
</wfs:Query>
</wfs:GetFeature>
I get a valid response and the data is properly displayed on the map.
When, however, I try to use a spatial filter in the request, like this...
<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; service="WFS"
version="1.0.0" xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd";>
<wfs:Query xmlns:ms="http://mapserver.gis.umn.edu/mapserver";
typeName="ms:omega">
<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc";>
<ogc:And>
<ogc:Intersects>
<ogc:PropertyName>the_geom</ogc:PropertyName>
<gml:Polygon xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326">
<gml:outerBoundaryIs>
<gml:LinearRing>
<gml:coordinates decimal="." cs="," ts="
">142.28349609375,-40.5255859375 142.2615234375,-43.49189453125
148.1501953125,-44.15107421875 149.40263671875,-39.44892578125
142.28349609375,-40.5255859375</gml:coordinates>
</gml:LinearRing>
</gml:outerBoundaryIs>
</gml:Polygon>
</ogc:Intersects>
<ogc:BBOX>
<ogc:PropertyName>the_geom</ogc:PropertyName>
<gml:Box xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326">
<gml:coordinates decimal="." cs="," ts=" ">135.45,-47.425
157.95,-36.175</gml:coordinates>
</gml:Box>
</ogc:BBOX>
</ogc:And>
</ogc:Filter>
</wfs:Query>
</wfs:GetFeature>
... one of the two following things will happen:
1. I get a "Internal Server Error The server encountered an internal
error or misconfiguration and was unable to complete your request." The
logfile says "Premature end of script headers: mapserv.exe, referer:
http://localhost/";.
2. This is the response:
<wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs";
xmlns:ms="http://mapserver.gis.umn.edu/mapserver";
xmlns:gml="http://www.opengis.net/gml";
xmlns:ogc="http://www.opengis.net/ogc";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd
http://mapserver.gis.umn.edu/mapserver
http://localhost/cgi-bin/mapserv.exe?map=E:/ms4w/Apache/htdocs/mapservertest/wfs.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=ms:omega&OUTPUTFORMAT=XMLSCHEMA";>
<gml:boundedBy>
<gml:Box srsName="EPSG:4326">
<gml:coordinates>-1.000000,-1.000000 -1.000000,-1.000000</gml:coordinates>
</gml:Box>
</gml:boundedBy>
</wfs:FeatureCollection>
Which one of the two possibilities happens appears to be random. Any ideas?
This is my mapfile :

Thanks for your help.
