Abstract: The present disclosure relates to methods and systems for performing response based cache redirection to a cache proxy. A device intermediary to a plurality of clients and a plurality of servers and in communication with a plurality of cache proxies, receives a request for content from a client. The request is for content from a server of the plurality of servers. The device forwards the request to the server. The device identifies a cache redirection policy that specifies an amount of bytes of a response to buffer to calculate a signature of the content of the response. The device computes the signature of the content of the response based on the amount of bytes of the response received from the server and buffered by the device. The device selects a cache proxy based on the computed signature and forwards the request of the client to the selected cache proxy.

Abstract: The present disclosure presents systems and methods for policy based redirection of network traffic, by an intermediary device, to a horizontally deployed WAN device. An intermediary receives a request from a client to access a server. The request was previously modified by a first WAN device to include information in a first option field of a transport layer. The intermediary may determine, responsive to a redirection policy, to send the request to a second WAN optimization device deployed horizontally from the intermediary, instead of the server. The intermediary transmits the request to the second WAN optimization device, while maintaining the information from the first option field. The intermediary device receives the request including the information in the first option field identifying the first WAN optimization device to the second WAN optimization device. The intermediary receives a modified request from the second WAN device, the modified request determined by the intermediary to be sent to the destination server.
