Multiple Layers Query with qlayer

[Selim HERNANDEZ]

Hello,

Does anyone know if it is possible to make a query on several layers when I 
am in itemfeaturequery mode ?

I have a layer containing areas and 2 others that contain areas.

I want to know  if I can know, with 1 query, whether the selected area (with 
a form) interacts with any of the areas of the 2 other layers.

According to the CGI reference, if the qlayer parameter is not set, all the 
layers are "queried" but It doesn't work.

thank you
