Abstract

Embodiments may be directed towards enabling one or more load balance servers to maintain connection flow persistence if the server initiates to the communication to a client. A packet traffic management device may (PTMD) intercept the request from the server and generate reverse persistence information. The PTMD may include a portion of the reverse persistence information in the request before forwarding the request to the targeted client device. The client device may send the response to the PTMD. The PTMD may employ reverse persistence information to identify the target server. The PTMD may remove the reverse persistence information from the response sent by the client and forward the response to the determined server. Removing the reverse persistence information may remove evidence that the PTMD intervened in the connection between the client and server.
