How to permanently redirect `http://` and `www.` URLs to `https://`?

Question

I have a Google App Engine project. On this project I have setup a custom domain and an SSL certificate. Therefore, I can use https://www.mysite.xxx, http://www.mysite.xxx and just the naked domain mysite.xxx.

Is it possible to permanently redirect the last two to always use the secure https:// domain using the developers console or do I just have to redirect in the code?

Answer 1

So you can add secure: always to your yaml file

always

Requests for a URL that match this handler that do not use HTTPS are automatically redirected to the HTTPS URL with the same path. Query parameters are preserved for the redirect. Example

- url: /youraccount/.*   
   script: accounts.app   
   login: required   
   secure: always
