-/**
- * Asynchronous version of SSLConnection.
- *
- * There are two concrete implementations of this class: AsyncSSLConnection
- * and AsyncSSLTunnelConnection.
- * This abstraction is useful when downgrading from HTTP/2 to HTTP/1.1 over
- * an SSL connection. See ExchangeImpl::get in the case where an ALPNException
- * is thrown.
- *
- * Note: An AsyncSSLConnection wraps a PlainHttpConnection, while an
- * AsyncSSLTunnelConnection wraps a PlainTunnelingConnection.
- * If both these wrapped classes where made to inherit from a
- * common abstraction then it might be possible to merge
- * AsyncSSLConnection and AsyncSSLTunnelConnection back into
- * a single class - and simply use different factory methods to
- * create different wrappees, but this is left up for further cleanup.
