We're having some problems with MapCache with a fully-seeded cache covering
a small geographic extent.
If the tileset definition doesn't have a restricted_extent, then any
requests outside the cache extents are supposed to return blank tiles, and
those blank tiles are being saved to the cache
If your tileset does not contain a source element, then it is
considered read only and the caches will never be updated. In that
sense you would have a slightly different mapcache.xml file for your
seeder than for your webserver.
As for returning blank tiles, you have the errors directive that
Thanks for the help but I think I'm misunderstanding mapcache at a more

mapcache itself does not do any pruning of the caches it has created,
but you can get the same effect by using a cache backend that supports
expiration (i.e. memcache).
Mapcache can fit your need, provided:

a memcache backend

I think I'll be good with the dimension and the disk cache. Unfortunately,

You can do this by commenting out the source block from the tileset
once the wanted tiles have been created. You'll probably also want set
error reporting to return blank images from that stage onwards.
