Abstract
A database client may establish a database session with a database server, including a session state, for a first TCP network connection through a first reverse proxy. A reattachment token is sent to the database client, and a database operation request is received from the database client through the first reverse proxy. Before or during execution of the database operation request (including any updates to the session state) an indication is received that the first reverse proxy will be terminated after a reattachment window. The server instructs the database client to perform a session reattachment and receives, from the database client, a session reattachment request, including the reattachment token, for a second TCP network connection through a second reverse proxy. The server verifies the reattachment token and resumes the database session with the database client, including the updated session state, for the second TCP network connection.
