Mark's initial work on the HTTP/2 connector has been using APR. Note
that APR doesn't handle the HTTP protocol, it just helps manage
sockets, pools, etc. The protocol needs to be built on top of those
building blocks. Please see the dev list (archives) for details. Just
search for "HTTP/2" subjects.

Tomcat supports Websocket since Tomcat 7, as long as you are running
on Java 7 or higher.

Correct. Using Websocket through certain proxies (e.g. httpd) is even
still sometimes tricky.
