A token for a webclient in communication with an HTTP server to access an email system is stored at a database by the HTTP server. If the HTTP server is unexpectedly unavailable, a backup HTTP server that next interacts with the webclient can locate the token for the webclient using identifying information for the webclient to locate a record in the database containing the token. The backup HTTP server can then provide seamless access to the email system for the webclient despite the loss of connectivity to the initial HTTP server.
