Need a simple sample mapcache.xml file that works with mapserver

I have a functioning mapserver installation runing on Ubuntu 14.04 and it's working fine. However, I would like to up the performance by putting mapcache in front of it.

I've installed mapcache, but I can't seem to create a valid mapcache.xml file.

I've found a number of 'complete' examples online, but I'm having trouble wrapping my head around all of the details.

Can someone point me to a minimal mapcache.xml file that simply forwards GetMap requests to mapserver and caches the resulting tiles? That would at least help get me started.

Thanks, Terry
