[Geomoose-users] Geomoose and mapcache

This is an example from probably 2011-2012.  Source WMS is just a normal
MapServer layer.  It is imagery so no worries about the metatiles to
attempt to get labels to work right.  I defined my own grid because I
found 512x512 tiles were more efficient than the 256x256 default which
required too many round trips to the server to fetch enough tiles to
fill a larger screen.

Map-Source:

    <map-source name='imagery' tiled='true' type='tms' width="512"
height="512" reference="off">
        <layer name="imagery at g512" title="Imagery"/>
        <url>https://my.server.com/mapcache/tms/</url>
        <param name="layername" value="imagery at g512"/>
    </map-source>

Map Cache:

<?xml version="1.0" encoding="UTF-8"?>

<mapcache>
   <cache name="disk" type="disk">
      <base>/srv/data/mapcache/disk</base>
      <symlink_blank/>
   </cache>

   <source name="imagery" type="wms">
      <getmap>
         <params>
            <FORMAT>image/jpeg</FORMAT>
            <LAYERS>imagery_zone14,imagery_zone15,imagery_zone16</LAYERS>
         </params>
      </getmap>
