MS WFS "Chaining"

[Bart van den Eijnden]

Hi,

this could be done I think. On your middle tier, you would have a 
Mapserver WFS client layer, which you also expose as a WFS server layer 
on the middle tier. The middle tier will then request the remote 
Mapserver WFS.

So in summary, on your middle tier you would have a WFS Client layer in 
your MAP file, and you would also expose your middle tier as a WFS 
server using the appropriate wfs server metadata.

Does this make sense :-) ?

Best regards,
Bart
