[OpenLayers-Users] Display legend

[Sophie GRAS]

Hi everyone 

I have a dumb question but i can't find the answer... 
I have a mapfile with several layers and I use openlayers to display them. 
In each layer I have some classes (representing percentage of the population) and I'd like to know how to display the legend of these classes using openlayers. 
If i embed the legend in the mapfile, it works well but the legend is displayed on each tile. Is there a way to act differently? 

Thanks
