US Patent 9965613 Method and system for user session discovery

Systems and methods are described to validate user connections to one or more application servers within a multi-tenant application system. A domain-level cookie at the client identifies any active connections for that client. As the client requests a connection to a particular application, the cookie is provided to a validation server that determines if any previously-established sessions with the multi-tenant system exist, and/or if such sessions remain active. If an active session already exists, then the client can be redirected to a particular server to continue the previously-established session. If no valid prior sessions are available, then the client can be validated and a new connection to an appropriate server can be established, as appropriate.
