Session Management

Introduction

To establish a session, the login command must be executed. This must be done before other RRI commands are transmitted. This records the identity and authorisation information for the duration of the session.

Clients should use the logout command to log out. After executing the logout command, the server terminates the session. After that, it is no longer possible to transmit further RRI commands to the server.

The following applies to session management:

• Live environment: 7 parallel sessions are possible per RegAcc.

• Test environment: 4 parallel sessions are possible per RegAcc.

• Both environments

  • Sessions without the login will be closed after 15 seconds.

  • After the login, a request must be sent at least every 5 minutes, otherwise the session will be closed.

  • If the maximum number of sessions is reached, no further sessions can be established and will be rejected with an error.

DENIC reserves the right to make changes at any time.
