Or, just a straight mode=legend request to the CGI if you are using MapServer.
You can pass in your extent, that will manage the scale-dependent layers.

Also, you might want to consider making a separate GetLegendGraphic WMS

Just an idea.

and search for untiled. There's a "WMS Untiled" example you can
view the source of. The singleTile option goes in the "options" object as
opposed the "params" object. Params get passed to the WMS service, options are
handled by OL.

usually set in OL.
Thanks for your help.
