Re: HTTPS for Java App


Hi Dan,

Thanks for the comments.
I understand how HTTPS flow works for CF with Load balancer like F5 (i.e HTTPS -> LB -> HTTP -> GoRouter -> HTTP -> Your App)

I read here ( that we can use HAProxy to enable HTTPS across the deployment.
Now since in our deployment we are using CF without HAProxy, I was wondering if something can be done from the Gorouter point of view to forward Https requests.

Do you have a different load balancer then?

I am trying to push a standalone Spring boot JAR (with embedded tomcat). The app starts properly but I can’t access it via https.

I have these settings for my spring boot app
remote_ip_header: x-forwarded-for
protocol_header: x-forwarded-proto

Within the app I have configured the tomcat to accept SSL connection using this sample

Can someone please point out what I am missing in order to get Https working for my app.

Usually this is not necessary. Your app would just need to listen on the port assigned to it (i.e. via PORT env variable) and it would listen for incoming HTTP traffic.

Do I need to enable something within the CF deployment ?

Usually what happens is that HTTPS traffic is terminated at your load balancer (that's why I asked if you had one above). The load balancer will then send a request to the go router which in turn directs the HTTP traffic to your app.

Ex: Browser -> HTTPS -> LB -> HTTP -> GoRouter -> HTTP -> Your App

You can tell if the traffic came from the user's browser via HTTPS by looking at the x-forwarded-proto header.
