Dear list,
I try to build a cascading WMS, which uses layers from a remote WMS.
This was easy to build in a mapfile by specify a Layer in the Layer section.
The remote WMS has over 400 layers and many goup layers in a layer tree.
My Question is: Is it possible to build a cascading WMS which loads all
Layers of a remote WMS (the complete Layer tree) without specify the
layers one by one.
Thank you for your help
Best Regards

If the remote WMS service is run by MapServer, you can actually call the
mapfile MAP object's NAME parameter, and MapServer will send a map image
containing all of its layers.
For example:
- WMS Service: http://demo.mapserver.org/cgi-bin/wms?
- has a MAP object with a NAME of "WMS_server"
- in the GetCapabilities response, this is shown as the first <LAYER>,
and in its <NAME> parameter
- so in the GetMap request, you can request all the layers with just
"&LAYERS=WMS_server"
A handy trick.
