I have a web application written in Go and load balanced by HAProxy. HAProxy also handles SSL/TLS termination. Currently the responses are all HTTP/1.1 and I'd like them to be HTTP/2. I've tried various things in haproxy.conf, but haven't been able to get it working.
I'm able to get a standalone Go server that handles its own SSL termination to use HTTP/2, but it looks like all current browsers only support HTTP/2 over TLS. Does this mean that I need to handle the SSL termination at the web app itself? Or is there some workaround that I don't know about so that I can continue terminating SSL at the load balancer and still use HTTP/2?
It looks like this is impossible, but I'm hoping there is a way to do it since otherwise I need to deal with SSL certificates at each web application rather than just at the load balancer.
