I developed a game running in facebook using GWT and Google app engine. following facebook new rule to supply secure canvas url, I am no longer able to run my application.

Does someone know What are the changes I should do to my application?

You can use https if you use the app-id.appspot.com domain instead of your custom domain.

Google has informed that it will start supporting https in custom domains but it is in test phase.

Ps: I have my canvas+page tab app workin with https.
