Session management in a mixed mode environment

A method for managing multiple versions of applications, comprising:

• receiving, at a first server executing a first version of an application, a request to generate new session data for a transaction requested by a user;
• determining, by the first server, that the first version of the application is unsuitable to process the request to generate new session data for the transaction requested by the user;
• determining, by the first server, an identity of a second server that is executing a second version of the application, the second version being different than the first version;
• and
• transmitting, by the first server, a hypertext transfer protocol proxy request to a second server associated with the second server identity.

• determining, by the first server, that the first version of the application is unsuitable to process the request to generate new session data for the transaction requested by the user;
• requesting, by the first server an identity of a second server that is executing a second version of the application, the second version being different than the first version;
• receiving, by the first server, the identity of the second server that is executing the second version of the application;
• and
• transmitting, by the first server, a hypertext transfer protocol proxy request to a second server associated with the second server identity.
