Abstract
Redirecting message flows to bypass load balancers. A destination intermediary receives a source-side message that includes a virtual address of a load balancer as a destination, and that is augmented to include a network address of a destination machine as a destination. The destination intermediary determines that a source intermediary should address subsequent network messages that originate from a source machine and that are associated with the same multi-message flow to the destination machine while bypassing the load balancer. The destination intermediary modifies the source-side message so the destination for the source-side message addresses the destination machine, and passes the modified source-side message to the destination machine. The destination intermediary receives a response from the destination machine identifying the source machine as its destination, and modifies the response so a source address identifies the virtual address of the load balancer, and dispatches the modified response to the source machine.
