[OpenLayers-Users] change projection layer dynamically

[Roald de Wit]

Hi,

I'm trying to find out if it is one layer (or layername) that you 
request or different layers (or layer names) for different zones. If it 
is the former, I would have no idea how to solve your problem. If it is 
the latter, the MapServer solution would be perfect. You would then 
define 3 layers in MapServer (it was three zones, wasn't it?) for every 
zone, each with their own projection. And in OpenLayers, you would 
create 1 WMS layer that requests those 3 layers from MapServer as if it 
was one layer. MapServer would do the reprojection for you.
If the WMS server is public and you can give me the URL and the layers 
you need, I'd be happy to try it out for you.

Cheers, Roald
