Abstract
Architecture that facilitates the capture of connection state of a connection established between a client and an intermediate server and forwards the state to one or more target servers. A software component at the target server (as well as the intermediate server) uses this connection state to reply back to the client directly, thereby bypassing the intermediate server. All packets from the client related to the request are received at the intermediate server and then forwarded to the target server. The migration can be accomplished without any change in the client operating system and client applications, without assistance from a gateway device such as a load balancer or the network, without duplication of all packets between the multiple servers, and without changes to the transport layer stack of the intermediate and target servers.
