    // Call SetSslCertRequirement to require that the SSL server certificate's domain
    // matches only the domain we are intending to communicate with.

    // In this example we will test with the URL https://wrong.host.badssl.com/
    // which intentionally has an SSL certificate that does not match "wrong.host.badssl.com"

    http.SetSslCertRequirement("SAN","wrong.host.badssl.com");

    // Also validate the server cert..
    http.put_RequireSslCertVerify(true);

    // Try sending the request.  It should fail within the SSL/TLS handshake
    // because the server's certificate does not match the domain "wrong.host.badssl.com"
    const char *html = http.quickGetStr("https://wrong.host.badssl.com/");
