1. In a distributed system that utilizes an HTTP request-response transport, a method of transferring an HTTP response as a plurality of different portions in order to conserve valuable system resources associated with validating and authorizing a corresponding HTTP request, the method comprising acts of:

sending a request message over an HTTP request flow for establishing a communication between endpoints in a distributed system;

receiving a first portion of a response over a corresponding HTTP reply flow, the first portion received at a first time period;

keeping the HTTP reply flow open in order to receive additional portions of the response;

without sending another request message, receiving a second portion of the response over the HTTP reply flow, the second portion received at a second time period different from the first time period; and

wherein one or more control messages are sent between the endpoints in a separate communication session in order to manage the established communication.
