The core interfaces and classes of the HTTP components. These deal with the fundamental things required for using the HTTP protocol, such as representing a message including it's headers and optional entity, and connections over which messages are sent. In order to prepare messages before sending or after receiving, there are interceptors for requests and responses.

HttpConnection	A generic HTTP connection, useful on client and server side.
HttpConnectionMetrics	The point of access to the statistics of an `HttpConnection`.
