I am setting up a new ssl tunnel using this library. Everything works great except for the ALPN negotiation. When I use firefox it sends h2-12, SPDY3, and HTTP1.1. I am getting a negotiation with HTTP1.1. If I use openssl with s_client and use the -alpn flag then the server will return h2-12 correctly.

What it looks like is openssl needs some way to specify what ALPN protocol should be negotiated. Using s_server there is a flag -alpn we can specify this. Is it possible to set something like that with this library?

Yes. I need to add an api to allow users to optionally enable features, like ALPN and SNI.
