The invention is directed to techniques for managing communication between a client and multiple servers over a network through an intermediary network device (e.g., content switch). In response to a request for content from a client, the network device selects a server to respond to the request. The network device includes a flow manager that manages the flow of data from the server through the network device to the client. In response to a second request, the network device may select a different server to respond to the request. In this case, the flow manager manages the flow of data from the new server through the network device transparently for the client, so that the client communicates only through the network device regardless of which server is providing the response to the requests.
