Need some help on WMS server.

[Fawcett, David]

Paul, 

I am guessing that you are getting the same image every time because you
have all three layers STATUS set to default.  Therefore, however you
request it, all three layers are drawing and the last one in your map
file is being drawn on top.  

I would suggest setting the layers STATUS to ON, and then using the
layers parameter in your GetMap request to select the layer that you are
interested in.  

David.

I'm bringing up a WMS server and I'm having problems serving different 
images from the same map file. It looks like only the last image of the 
3 is being served.

The server is at

http://www.ccalmr.ogi.edu/cgi-bin/mapserv?map=/usr/local/apache/mapserve
r/wms.map

There are 3 images served, one per layer, and each is different (I've 
verified this) but it seems that in every WMS client I use, the same 
image shows up no matter which layer I select (the last image).

Any suggestions appreciated.

Thx,
