Hello list,
We have a cascading WMS using Mapserver as a client to request maps from
another Mapserver. We have it working well, however we are wondering whether it
is possible to do a GetLegendGraphic request to this top level Mapserver and
have it in turn pass on that request to the underlying mapserver, which would
then return the legend graphic.
Here's a snippet of our 'top level' Mapserver mapfile, which sits on our public
server:
...
LEGEND
STATUS OFF
KEYSIZE 30 15
KEYSPACING 10 10
LABEL
COLOR 0 0 0
FONT 'arialbd'
TYPE truetype
SIZE 10
END
END
LAYER
NAME 'coastpoly'
TYPE RASTER
CONNECTIONTYPE WMS
CONNECTION "http://ourprivateserver/wms?";
PROCESSING "CLOSE_CONNECTION=DEFER"
METADATA
"wms_name" "coastpoly"
"wms_title" "Topographic Coastline
Polygons"
"wms_server_version" "1.1.1"
"wms_format" "image/png"
"wms_srs" "EPSG:2193 EPSG:27200
EPSG:4326"
END
END
...
And a snippet from our underlying Mapserver:
...
LEGEND
STATUS OFF
KEYSIZE 30 15
KEYSPACING 10 10
LABEL
COLOR 0 0 0
FONT 'arialbd'
TYPE truetype

I think we may be missing something obvious here, so any ideas greatly
appreciated... :)
