"Cache anonymous pages" interferes with https redirect

I was able to generally reproduce this by going to the https login page, logging in, logging out, then going to http version. With "cache anonymous pages" turned on, it would not redirect to https.

Some test curl calls may shed some light...

When it's off, and it works:
$ curl -I http://www.example.com

Maybe this is not necessarily a bug, but at the very least it should be an installation or documentation issue.

Thanks.
