* This test case test that:
* 1) any directory can be added to the path lookup (such as /tmp) by
* calling the right event
* 2) that a file we know exists gets cached so that the lookup/verification
* of actual existence doesn't occur again when a subsequent request comes in
*
* The second point verifies that the cache works. If the cache wouldn't work
* the default PNG would be served
