(Swift 3,4,5...) SSH using HTTP Proxy

Note: This example requires Chilkat v9.5.0.51 or greater.

Demonstrates how to connect to an SSH server through an HTTP proxy. (Connects through a generic proxy of type: HTTP/1.1 using the CONNECT method.)

    let ssh = CkoSsh()!

    // To connect through an HTTP proxy, set the HttpProxyHostname
    // and HttpProxyPort properties to the hostname (or IP address)
    // and port of the HTTP proxy.  Typical port numbers used by
    // HTTP proxy servers are 3128 and 8080.
    ssh.httpProxyHostname = "www.my-http-proxy.com"
    ssh.httpProxyPort = 3128

    // Important:  Your HTTP proxy server must allow non-HTTP
    // traffic to pass.  Otherwise this does not work.

    // Connect to an SSH server via an HTTP proxy:
    var hostname: String?
    var port: Int

    // Hostname may be an IP address or hostname:
    hostname = "192.168.1.108"
    port = 22

    var success: Bool = ssh.connect(hostname, port: port)
    if success != true {
        print("\(ssh.lastErrorText!)")
        return
    }

    // Your application is now connected to an SSH server 
    // through an HTTP proxy. 
    // ..
