| /** |
| * 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. |
