[mapserver-users] mapcache question

The demo file in master parses correctly. Again, if you're having an
issue it is either because you have made invalid (in the xml sense)
modifications to it, or that your apache user doesn't have access
rights to it (or to the directories above it).

I thought MapCache did support native MapServer mode=map as a source which could useful if GDAL supports WMTS and you could create a corresponding MapServer layer.

As planned, Mapcache should work as a WMTS client down towards target 1 and WMTS server up against target 3, ie. kind of a proxy with crs reprojection and basic auth. Anyway, does this make any sense at all, or is the draft totally irrational?
