This isn't what minzoom/maxzoom are for. These switches are used in cases where your data doesn't cover the whole grid or has a resolution that makes it useless in high zoom levels. With them you can prevent your cache from being filled with useless tiles. > I would like it > to send the request to the source if it is beyond the maxzoom value. Is > there a way to do this? Surely not. I think you misunderstood what a cache is and how it works. You should use mapcache_seed in delete mode to throttle the cache size. Of course it would be great if mapcache would itself gather statistics and control the cache but that would introduce overhead and serious problems with some cache types (especially the popular "disk" type). _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
