[mapserver-users] Mapcache - Composite cache problem

[thomas bonfort]

OK, got it, I think :)
the disk caches by default encode the tileset name in the file path it
creates, so your topo2matrikkel tileset will never be able to read tiles
belonging to the topo2 tileset. If you want to be more clever than
mapcache, you can use your own file template (<cache type="disk"
layout="template">), but beware that mapcache will then not prevent you
from shooting yourself in the foot if you omit to add template tags (in
your case you would need to at least add a {grid} element, and be sure to
not reference that <cache> from other tilesets)
