[mapserver-users] layer handling in Mapserver WMS clients

[Schylberg Lars]

Hi,

I have a follow up question on my question yesterday.  I would like to have the layers in the main called mapfile to be set layers in the client WMS calls.
The WMS client documentation says, http://mapserver.org/ogc/wms_client.html :

"wms_name" metadata - comma-separated list of layers to be fetched from the remote WMS server. This value is used to set the LAYERS and QUERY_LAYERS WMS URL parameters

When I call the MAP_MAIN I would like to call it like this:

http://localhost/cgi-bin/mapserv?map=/var/www/html/map2/MAP_MAIN.map
&SERVICE=WMS&REQUEST=Getmap&VERSION=1.1.1
&LAYERS=base,marks,text&srs=EPSG:4326&BBOX=9.624750,52.33333,30.333333,66.500000
&FORMAT=application/openlayers&WIDTH=2000&HEIGHT=1100

or  &LAYERS=base,text   or  &LAYERS=base

Is the mechanism similar to the srs handling?
How do I expose the layers in the wms clients map files?  Right now I use GROUP to define the layers and that works when I call it directly.  Or is it so that I have to expose the layers with
WMS_LAYER_GROUP in the wms-server mapfiles that are called as clients? I haven't been successful with that! I have several clients with the same layer structure and one with just default.
