 * The installation of WP Super Cache for one of our clients, has been producing
   the error “cURL error 56: Failure when receiving data from the peer” when running
   a test.
 * The client uses Heart Internet to host their website, who have responded with…
 * “I have checked this for you, and the error that you’re receiving is due to loopback
   connections being made to the server, this means that the plugins is trying to
   call a http request to the same server which is disabled on our system for security
   reasons.
 * You would need to check with the authors of the plugin, to see if there is a 
   way that you can disable the loopback connections being made from the plugins
   so this can work properly on our system.”
 * Are you able to provide any further information on this?
