It sounds right.

According to the same situation, how does http2 protocol force other
virtual servers to process certificate (ssl handshake).

Example:

server {
listen 443 http2;
a.com;
ssl_certi....;
}

server {
listen 443 http2;
b.com;
ssl_certi....;
}

We assume sni is 'a.com', then the connection contains different requests
with different domains.
That b.com will escape from ssl handshake. In fact, we need it to do the
ssl handshake.

Thanks.
