Hi,

I have been playing with vendor parameters with some WMS services for making layers \
more dynamic.  For example  \
http://188.64.1.61/cgi-bin/ms_ows?REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.1&WIDTH=563&H \
EIGHT=437&LAYERS=default,osm_pisteet&TRANSPARENT=TRUE&FORMAT=image/png&BBOX=-369151.98 \
300283286,6597900.0,1511076.628895184,8057331.444759207&SRS=EPSG:3067&STYLES=&sql=highway='bus_stop'


Problem is that properly behaving WMS clients are taking the GetMap URL from the \
GetgCapabilities document and that is fixed by the wms_onliresource metadata in a \
mapfile. Some WMS clients (at least OpenJUMP, QGis and Kosmo) can be configured to \
add the extra parameters also into GetMaps but some others don't.  The OpenLayers \
demo client that comes with Mapserver 6.0.1 is one of those. It creates the demo \
layer with this code: var mslayer = new OpenLayers.Layer.MapServer( "MapServer \
Layer",  "[mapserv_onlineresource]",
             {layers: '[layers]'},
             {singleTile: "true", ratio:1} );

Does anybody know a simple way for transferring the same vendor parameters which are \
used in the GetCapabilities request into the GetMap OnlineResource element of the \
response?
