When I perform an asynchronous HTTP operation that returns an error_code then I prefer that the error_code contains a unified response, i.e. an HTTP status code, a system error code (e.g. network problem), or an internal library error code.

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.
