A method of replicating on a test server a production load of a production server. The method can include creating the production load on the production server by processing client requests received from clients. The method further can include, while the client requests are processed, via a processor, in real time, replicating the production load to generate a replicated production load that represents the client requests and defines state information representing unique states formed between the production server and the respective clients. The method also can include, in real time, communicating the replicated production load in order to replicate the production load on the test server.
