A nice thing about HTTP (if there is any such thing) is that the HTTP
"message" can be modeled as a self contained object.

The low-level result of the asynchronous operation (for example
boost::asio::error::connection_reset) reflects metadata about the HTTP
message and should not be part of that container.
