[Mapserver-users] Re: change parameters via URL

[Jan Hartmann]

I'm not sure (I have not used WMS much), but I don't think you can mix 
WMS calls (map=...&request=... etc) with regular MapServer 
URL-parameters (map_layer_class=... etc). I vaguely rememember having 
tried once and not succeeded. Can anyone shed light on this?
