I\'ve read How to configure playframework server to support ssl and I also tried to follow http://www.playframework.org/documentation/1.1.1/releasenotes-1.1#https but it doe
One thing we did was to use AWS ELB to handle our SSL, then setup the SSL forwarding (HTTP -> HTTPS) using a plays filters. The main benefit, takes the SSL load off your server and you don't have to run Apache or Nginx in front of play (as some solution point out).

I also write a bit more about it in my blog: http://www.mentful.com/2014/05/25/play-framework-filter-for-aws-elastic-load-balancer-forward-http-to-https/
