/* It would be even better if $cache->getFile() is used instead to get the cache's filename 
for you to parse into a URL redirection. This method would make use of any client-side 
caching and eliminate the overhead of loading and parsing the cache file.

IMPORTANT NOTE: Make sure that you keep caches that may have sensitive information in a 
non-www accessible location (see documentation on how to have caches stored in several 
different locations)

Pseudo alternate method:
$url = yourPathToURLFunction($cache->getFile());
header("Location: $url");
