Hi, thank you. Of course it should not compromise other applications. Alternatively I could try to use an SLD, which is an optional WMS parameter. Probably you already had the discussion. It seems that none of the optional parameters are actually forwarded to a remote WMS. Since a GeoTools routine is used in this context (org.geotools.coverage.grid.io.AbstractGridCoverage2DReader), I am puzzled and don't even know how to hack this, let alone a usable implementation of SLD forwarding. In the current doc I read that styling remote layers is not possible (as of yet).

In my workflow I need to forward also custom parameters not known to WMS or GeoServer The WMS I am talking of renders heat maps, a feature that is currently not available and describable in OGC service stack. It supports GetMap and GetCapabilites requests but requires some additional parameters which are currently swallowed by the cascaded WMS feature. Time available and help appreciated. Yes, all parameters that are unknown to GeoServer are ignored at the request parsing level and are lost. I'm also considering a case in which you are cascading multiple wms servers, just blindly sending down all the extra params seems problematic, the same vendor param could be have a different meaning for the two servers, or one of the might simply throw an exception (though the WMS spec says to ignore the params that are not understood).
