Abstract: The present disclosure presents systems and methods for maintaining original source and destination IP addresses of a request while performing intermediary cache redirection. An intermediary receives a request from a client destined to a server identifying a client IP address as a source IP address and a server IP address as a destination IP address. The intermediary transmits the request to a cache server, the request maintaining original IP addresses and identifying a MAC address of the cache server as the destination MAC address. The intermediary receives the request from the cache server responsive to a cache miss, the received request maintaining the original source and destination IP addresses. The intermediary identifying that the third request is coming from the cache server via one or more data link layer properties of the third transport layer connection. The intermediary transmits to the server the request identifying the client IP address as the source IP address and the server IP address as the destination IP address.

Abstract translation: 本公开提供了用于在执行中间缓存重定向的同时维护请求的原始源和目的地IP地址的系统和方法。 中介接收来自发往服务器的客户端的请求，该服务器标识客户端IP地址作为源IP地址，服务器IP地址作为目的地IP地址。 中介将请求发送到缓存服务器，请求维护原始IP地址，并将缓存服务器的MAC地址识别为目的MAC地址。 中继器响应于高速缓存未命中从缓存服务器接收请求，所接收的请求保持原始源和目的地IP地址。 识别第三请求的中介通过第三传输层连接的一个或多个数据链路层属性从缓存服务器发出。 中介向服务器发送将客户端IP地址标识为源IP地址和服务器IP地址作为目标IP地址的请求。
