Systems and methods for managing multiple versions of applications executing on servers in a server pool are provided. A request to generate new session data for a transaction requested by a user is received by a first server executing a first version of an application. A determination is made that the first version of the application is unsuitable to process the request. An identity of a second server executing a second version of the application is requested by the first server in a server pool comprising one or more servers, and an appropriate second server is selected. The first server transmits a hypertext transfer protocol proxy request to the selected second server, which generates the new session data.

Session management in a mixed mode environment

Systems and methods for managing multiple versions of applications executing on servers in a server pool are provided. A first server executing a first version of an application loads session data associated with a second, different version of the application. An error is detected based on the difference between the first version and the second version. A second server executing the second version of the application is selected by the first server in a server pool comprising one or more servers. The first server transmits a hypertext transfer protocol proxy request to the selected second server, which successfully processes the session data and handles the request without error.
