<div dir="ltr">John,<div style>The configuration seems ok, you might want to remove the threaded_fetching part as it will only help in very specific scenarios.</div><div style>As for the root issue, are your tilesets fully preseeded or are they populated on demand? KML superoverlays are organized in a tree, i.e. to access a tile at zoom level N you first need to access all parent tiles from level 0 to N-1; on an unseeded tileset with a slow wms backend this might be a very long wait. Also please check the apache error log for any mapcache related messages.</div>

Not sure my earlier query made it to the list.<br>
<br>
I'm using MapCache to serve for some satellite image products. It sort of works: the tms and wmts browsers at /mapcache/demo show full coverage of my data area, and let users zoom in to see full resolution image mosaics. But the KML superoverlay (my reason for using MapCache) only displays in Google Earth when I'm zoomed very far out (so that the entire globe is not much bigger than a golf ball on my screen). If I zoom in, the image usually disappears; though sometimes when zoomed in I do see [only] the right (east) half of my tileset, at a very low resolution.<br>
<br>
Do you see anything wrong with my mapcache.xml (below)?<br>
Is there anything else I should be checking?<br>
<br>
(I'm using a simple disk cache in /tmp, with mod_mapcache from the Ubuntu libmapcache 1.0.0-3 package; Mapserver 6.2.1 is on the same machine, running in 64-bit Ubuntu 12.04. Mapserver works fine, and reports no errors [I think]. My client is Google Earth 7.)<br>
<br>
Thanks for taking a look,<br>
