SSL for GAE domains

Using JADS Web Traffic Manager, it is fairly easy to provide an SSL secured version of your Google App Engine app on your domain.
  1. Download the Web Traffic Manager.

  2. Create https_routes.txt containing:
    ^/ ->[Protocol=https]
    (where myapp is the name of the GAE app)

  3. Create a Java key store and import your domain's SSL certificate.

  4. Launch the Web Traffic Manager on a server mapped to your domain
    java -jar wtm-core.jar -cp wtm-http.jar -https 443
All https:// traffic reaching your domain will now be routed securely to the Google App Engine, users will remain on your domain.
