Subject: https: use `servername` in agent key
X-Git-Tag: v4.2.5~58
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=751fbd84dd200d2462eefe854316055332819a4e;p=platform%2Fupstream%2Fnodejs.git

https: use `servername` in agent key

https requests with different SNI values should not be sent over the
same connection, even if the `host` is the same. Server may want to
present different certificate or route the incoming TLS connection
differently, depending on the received servername extension.
