[mapserver-users] mapserver as a tiling client for an untiled WMS

Dear List,

In my mapserver maps (served as a WMS) I'd like to add a layer from an 
untiled WMS (not under my control).
Simple enough, but this WMS restricts the returned images to a maximum 
number of pixels, and also restricts the scale (only scales larger than 
a certain scale is allowed). The maps I'd like to make of course exceeds 
the limit of pixels.

The solution seems simple enough: chop up the request in a series off 
requests, and stich the returned images together. So basically this is a 
tiling approach. To complicate things a bit, the service is not 
spherical mercator.

I guess I have to use the GDAL-WMS minidriver and/ or TileCache, but 
I've not a clue to how to proceed. Can anyone please point me to some 
usefull examples or give me a short explanation to work from?

any help again greatly appreciated ...

MArco
