We are not using sqlite db for caching type<br></div><div><br></div><div>1. We are using<b> caching type as File</b>(default cache type <b>file</b> and it uses a single file for each tile). Defaults to <code><span>tc</span></code> which uses a TileCache compatible directory layout <b>(<code><span>zz/xxx/xxx/xxx/yyy/yyy/yyy.format</span></code>)</b>. <br></div><div><br></div><div>2. We have deployed MapProxy in <b>Multiple Servers/Instances and all the servers have common storage</b> where the data/images are stored.</div><div><br></div><div>3. We have created layer definition and Caching details <b>same in all the servers</b></div><div><br></div><div>4. Now we want to cache the layer in all the servers (running multiple instances in each server - number of instances varies based on server configuration and storage type)by dividing the area by grid wise(<b>1deg *1deg or 2 deg*2deg).</b><br></div><div><b><br></b></div><div>We have used MetaCarta Tilecache (<a href="http://tilecache.org/">http://tilecache.org/</a>) and used the above process and executed caching multiple instances for the same zoom level and same layer. This helped us realize the caching of the layer quickly.</div><div><b><br></b></div><div><b>Can we create the cache using MapProxy in multiple instances for the same zoom level and same layer?</b></div><div><b><br></b></div><div><b>I have gone through the Manual, but not able to find the method.
