 * Hi,
 * I am using the plugin with a redis cache wordpress installation.
 * For some reason, after a while the referer check feature isn’t working, and I
   am able to use the link outside my site. The problem gone, after I flush the 
   redis cache.
 * I am not sure what’s wrong though, so perhaps maybe you could help?
 * Cheers
