Not sure if this would work for you Paolo, but IF all layers come from
the same service, the web-client could try to collect all layers from
that service in the right order and fire it as one WMS request.

BUT off course this makes it more difficult to implement a layertree in
which you want to be able to show/hide individual layers. You will have
to fire the layer collection EVERY time the visibility of one of the
layer changes. ( I once coded a java-applet doing this :-) )

IF it is a one service project, this seems a viable option to implement?
