ABSTRACT:
A system for servicing a request from a client includes at least two proxy servers, each having a corresponding proxy server configured as a buddy proxy server, and being adapted to act as a primary proxy server for servicing the request and to forward the request to a backend server. The system includes a load balancer adapted to: forward the request to a primary proxy server; forward the request to a failover proxy server in the event of failure of the primary proxy server; and forward a response from the primary proxy server or the failover proxy server to the client. The system includes a backend server adapted to receive a request from a proxy server and to send a response to the proxy server. The failover proxy server is adapted to process the request depending on a status of a matching previously stored request.
