changing DATA parameter in mapfile via URL

[Dylan Beaudette]

Is is possible to change the 'DATA' parameter via a URL-style variable such
as:

...&map_layername_data="xxx.shp"

i am able to change every other property of this layer, but not its data
source.

if this is not possible, does anyone know of some kind of work-around?

i am trying to use a single map file for numerous different shape files...

thanks in advance!
