Replicating on a test server a production load of a production server. The production load can be created on the production server by processing client requests received from clients. While the client requests are processed, in real time, the production load can be replicated 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. In real time, the replicated production load can be communicated in order to replicate the production load on the test server.
