[QGIS-Developer] QGIS Server request extra parameters as variables for expressions

[Arnaud Morvan]

Hello,

I would like GetMap and GetFeature request extra parameters to be 
accessible as variables in server.

So we could define, in QGIS project, a variable "floor", used to filter 
layers.

On desktop side, we could have a desktop plugin named FloorSlider to 
change the "floor" value.

And on the server side, the floor value could be passed as extra parameter.

So it would be easy to handle multi-floor layers in a project file.
