Demonstrate how to connect to a web server over HTTPS where that server requires that the client present a certificate to prove who (s)he is. Unlike with the HTTPS request with authentication task, it is not acceptable to perform the authentication by a username/password or a set cookie.

This task is in general useful for use with webservice clients as it offers a high level of assurance that the client is an acceptable counterparty for the server. For example, Amazon Web Services uses this style of authentication.

import httpclient, net
var client = newHttpClient(sslContext = newContext(certFile = "mycert.pem"))
var r = client.get("https://www.example.com")
