check_http fails to redirect to secure sites

Starting this morning two of the sites I monitor failed, www.sprint.net and
www.sprintv6.net.  After some testing it’s become clear to me that
check_http doesn’t currently redirect to secure sites, even with the use of
the '-f follow' command.  I guess Sprint turned on redirection to the secure
version this morning.

 

Not sure whether to call this a bug or working-as-designed, but I’m request
the follow feature be enhanced to allow redirection to the secure version of
host.

 

I'm running check_http version 1.4.15.

 

Here's a copy of my tests:
