How to disable HTTPS?
When I make a request to my app for the first time using http, it responds with http, but if I put in a request with https, I'm not able to switch back to http (e.g., my browser redirects to https all the time).
By default, all applications are accessible via http and https. You shouldn't have to do anything differently unless you want to force https traffic as per https://openshift.redhat.com/community/kb/kb-e1044-how-to-redirect-traffic-to-https
There is a side affect to supporting both as per https://bugzilla.redhat.com/show_bug.cgi?id=825334 When you point your browser to https, then it won't switch back to http until you clear your browser cache.
