Sally, To make it easier for people to help you figure this out, I would suggest including the request string produced by OpenLayers and your mapfile text.

What I'm trying to do is so basic, I'm sure that many have done this, yet I've been unsuccessful. I thought this would be easy. With much searching I have found similar questions, but nothing actually answering or showing a working example of this. I'm using mapserver 6.2.1 and the current OpenLayers.js. I can run the wfs.map file using shp2img and get a valid response from mapserver, I can run non-spatial filters using my OpenLayers WFS call to mapserver. The POST request sent to mapserver with the spatial query looks fine, but I simply get the not very helpful "premature end of script headers : mapserv" in response. The spatial input is a hand-drawn polygon in OpenLayers and the intersection at the mapserver end is a postgis table containing a polygon field. The table is large, but a spatial restriction should always yield a manageable number of records. Without a spatial restriction in the filter, I've noticed that mapserver tried to load all the data, so have currently restricted it to 100 records for testing/debugging. I'm assuming once I get the spatial filter that this will restrict the number of records retrieved on the server side. I have some assumptions, but as I said I've not been able to find a working example of this online, maybe because its too simple and everyone but me has it working? Should what I'm trying to do work or am I just beating my head against the wall? It doesn't seem that this should be so hard... Sally
