[MapProxy] MapProxy works with dynamic Legend?

[RK]

Hello everybody,

I had a question about legend images in MapProxy.

Is it possible to set up dynamic legend images in MapProxy? Does that mean that MapProxy sends the parameters Width, Heigth and BBOX to the
legend url?

Since I have defined the WMS source source as MapServer in Mapproxy, I want Mapproxy not to cache the legend images and to forward the requests
to MapServer.

Can someone help me there?

Regards Robert
