Request executor in the request execution chain that is responsible for implementation of HTTP specification requirements. Internally this executor relies on a HttpProcessor to populate requisite HTTP request headers, process HTTP response headers and update session state in HttpClientContext.

Further responsibilities such as communication with the opposite endpoint is delegated to the next executor in the request execution chain.
