class NetSSL_API HTTPSClientSession: public HTTPClientSession
/// This class implements the client-side of
/// a HTTPS session.
///
/// To send a HTTPS request to a HTTPS server, first
/// instantiate a HTTPSClientSession object and
/// specify the server's host name and port number.
///
/// Then create a HTTPRequest object, fill it accordingly,
/// and pass it as argument to the sendRequst() method.
///
/// sendRequest() will return an output stream that can
/// be used to send the request body, if there is any.
///
/// After you are done sending the request body, create
/// a HTTPResponse object and pass it to receiveResponse().
///
/// This will return an input stream that can be used to
/// read the response body.
///
/// See RFC 2616 <http://www.faqs.org/rfcs/rfc2616.html> for more
/// information about the HTTP protocol.
///
/// Note that sending requests that neither contain a content length
/// field in the header nor are using chunked transfer encoding will
/// result in a SSL protocol violation, as the framework shuts down
/// the socket after sending the message body. No orderly SSL shutdown
/// will be performed in this case.
///
/// If session caching has been enabled for the Context object passed
/// to the HTTPSClientSession, the HTTPSClientSession class will
/// attempt to reuse a previously obtained Session object in
/// case of a reconnect.
