Yeah the Protocol aware notation should work here as well. And true you should just rewrite http to https and it should work.
I haven´t had any problems with f3 and https so far. One thing which comes to my mind is Cookie handling. See: http://stackoverflow.com/a/22222151/1474777
I ' ve never checken how f3 sets cookies .... But never had problems either ...
