I am attempting to configure our internal GeoServer to cascade an external WMS server. The external server has some custom properties which need to be passed when making a call to that WMS.
http://externalwms.com/?VERSION=1.3.0&REQUEST=GetMap&LAYERS=ENC&CRS=EPSG:4326&BBOX=53.8,8.4,54.1,9.2&CSBOOL=384&CSVALUE=,,,,,3&WIDTH=1280&HEIGHT=800&FORMAT=image/png
as you can see, the custom properties are
&CSBOOL=384
&CSVALUE=,,,,,3
I am unsure how to configure our WMS service with these parameters so the remote service is called with them.
I tried adding them to the service definition / GetCapabilities without luck. it appears to ignore the additional parameters.
I then tried to configure in the layers but there is no clear place to add custom parameters.
How can I achieve this?
