[mapserver-users] [mapcache] Add OSM into TileCache

[Stephen Woodbridge]

Hi Hanks,

I have moved this discussion to the mapserver list so sub to it if you 
have not already.

mapcache does not support input source s other than WMS at the moment. 
BUT there is a hackish way to work around that if you need to:

You should be able to setup a mapserver WMS service with a LAYER using 
GDAL 1.7.0+ configured to pull OSM tile server as input.

So mapserver requests the OSM tiles and assembles an image in response 
to a WMS request it receives from mapcache and mapcache then chops the 
image back into tiles and stores them in the cache in response to your 
OpenLayers making tile requests to mapcache.

I have not done this but I suspect that it would work very well and 
while it sounds convoluted it should not be that hard to figure out the 
details if you ask on this list when you have a problem.
