[mapserver-users] mapcache - rendering higher level tiles from lower level tilesets

[Travis Kirstine]

I have a fully seeded cache of tiles to level 19 and no longer can access
the original WMS source. Is it possible to generate a tileset using a
memcache for layer above level 19 using the seeded cache as source?

Something like this


 <cache name="disk" type="disk">
    <base>/home/caches</base>
    <symlink_blank/>
 </cache>

  <cache name="memcache" type="memcache">
    <server>
     <host>localhost</host>
     <port>11211</port>
     </server>
   </cache>


    <tileset name="Fully_Seeded_to_19_cache">
      <!--source>layer</source-->
      <cache>disk</cache>
      <grid>gmaps</grid>
      <format>mixed</format>
      <metatile>1 1</metatile>
      <metabuffer>0</metabuffer>
    </tileset>

    <tileset name="Memcache_greater_than_19_cache">
      <source></source>
      <cache>memcache</cache>
      <grid>gmaps</grid>
      <format>mixed</format>
      <metatile>1 1</metatile>
      <metabuffer>0</metabuffer>
    </tileset>
