[mapserver-users] MapCache: Disabling WMS requests for fully-seeded caches?

[John Taranu]

We have a fully seeded cache that was fully seeded to a polygon outline.
The intent is to serve the tileset through a variety of services (WMS, TMS)
using mod-mapcache.  

 

Tiles that are outside the polygon outline but still within the polygon
bounding box should be blank tiles.  However, a request for one of these
tiles results in a call to that tileset's WMS source.  This creates
considerable overhead by starting up MapServer and writing the resulting
tile to the cache.  Is there any way to disable the WMS calls for these
blank tiles, and instead short-circuit the request to return a blank?  That
is, once a tileset has been fully seeded, is it possible to disable any
further calls to the WMS, so that requests for tiles that are not in the
cache return a blank?
