The pool consists of 0 or more connections at any time and can grow to a maximum number of connections set by the application. The connection pool only represents outgoing connections and is not used to represent incoming connections as they are not used for pooling.

It allows a user to add the message body and content type on a service request. Also provides an overload to send a custom "To" Header and accepted Headers.
