Abstract
Some embodiments provide a director agent, a server agent, and a specialized hand-off protocol for improving scalability and resource usage within a server farm. A first network connection is established between a client and the director agent in order to receive a content request from the client from which to select a server from a set of servers that is responsible for hosting the requested content. A second network connection is established between the server agent that is associated with the selected server and a protocol stack of the selected server. The first network connection is handed-off to the server agent using the specialized hand-off protocol. The server agent performs network connection state parameter transformations between the two connections to create a network connection through which content can be passed from the selected server to the client without passing through the director.
