Devs,
Please find RFC97:

http://mapserver.org/development/rfc/ms-rfc-97.html

A bit short for an RFC, but a bit too long for just a ticket... This RFC basically allows serving tiles from high zoom levels by upscaling lower zoom level ones at request time, thus avoiding to fill up the caches with upscaled data.
Note that the RFC also provisions the usage of proxying these high zoom-level tiles to the source WMS instead of reconstructing them from the lower level tiles (use-case: the WMS is fast enough when zoomed-in, but needs caching when far away). This isn't implemented yet, but should be a contribution by the OpenWebBlobe folks in some future.

best regards,
thomas
