Abstract

A network system uses a staging server. The network system comprises an existing server and a client device that transmits session traffic comprising an HTTP request message. The HTTP request message is duplicated to form duplicated HTTP request messages. It is determined whether the HTTP request message has a first session identifier. If so, a mapping relation between the first session identifier and a second session identifier is searched for. The duplicated HTTP request messages to the existing server and the staging server, respectively, are transmitted, wherein the session identifier of the HTTP request message to the staging server is replaced with the second session identifier based on the first session identifier and the mapping relation. One embodiment may also comprise receiving an HTTP reply message from the existing server and an HTTP reply message from the staging server. The HTTP reply message from the existing server and the HTTP reply message from the staging server are compared.
