[mapserver-users] MapCache - A way to delete a whole zoom level ?

[Stephen Woodbridge]

Ludovic' problem is that he is out of disk space so that is probably not 
going to work for him. If he can not free some space to start with it is 
likely he will have to delete the whole cache.

Ludovic, You might want to write an enhancement request to mapcache, 
that requests each zoom level be put into a separate database file so 
that it is easy to monitor the disk space each zoom level uses and to 
quickly remove a zoom level with a system level file delete.
