[mapserver-users] WMS GetMap request - incorrect layer ordering

[John Cartwright]

Hello All,

I'm finding a difference between the image produced by shp2img and a WMS GetMap request.  The image produced by shp2img looks as I expect honoring the order in which LAYERS are defined in the map file and the STATUS value.  However, the WMS request does not seem to respect the order of the LAYERs, always drawing the polygons first regardless of the order defined in the map file or that of the WMS LAYERS request parameter.  

Here's a representative WMS request:

http://localhost/cgi-bin/basicworld?request=getmap&service=wms&width=500&height=250&bbox=-180,-90,180,90&srs=EPSG:4326&version=1.1.1&layers=countries&format=png

Both the cities and countries layers display as you'd expect, but the countries draw on top of the cities contrary to what I'd expect and different that in the shp2img output. 

I'm using mapserver version 6.0.1 and I've tried various versions of WMS.  Can someone please examine the map file below and point out what I'm doing wrong?

Thanks!
