Session reliability policy settings

The session reliability section contains policy settings for managing session reliability connections.

Session reliability connections

This setting allows or prevents sessions to remain open during a loss of network connectivity. Session reliability, along with auto client reconnection, allows users to automatically reconnect to their Citrix Receiver sessions after recovering from network disruptions. By default, session reliability is Allowed.

On Citrix Receiver for Windows 4.7 and later, the settings in Studio are enforced on the client. Citrix Receiver Group Policy Object on the clients are overridden by Studio policy. Updates to these policies in Studio synchronize session reliability from server to client.

Note:

  • Citrix Receiver for Windows 4.7 and later and Citrix Workspace Apps for Windows - Set the policy in Studio.
  • Citrix Receivers for Windows earlier than 4.7 - Set policies in Studio and the Citrix Receiver Group Policy Object template on the client for consistent behavior.

Session reliability keeps sessions active and on the user’s screen when network connectivity is interrupted. Users continue to see the application they are using until network connectivity resumes.

With session reliability, the session remains active on the server. To indicate that connectivity is lost, the user display becomes opaque. The user might see a frozen session during the interruption and can resume interacting with the application when the network connection is restored. Session reliability reconnects users without reauthentication prompts.

If you use both session reliability and auto client reconnect, the two features work in sequence. Session reliability closes (or disconnects) the user session after the amount of time specified in the session reliability timeout setting. After that, the auto client reconnect settings take effect, attempting to reconnect the user to the disconnected session.

By default, session reliability is Allowed.

To disable session reliability:

  1. Start Citrix Studio.
  2. Open the Session Reliability connections policy.
  3. Set the policy to Prohibited.

Session reliability port number

This setting specifies the TCP port number for incoming session reliability connections.

By default, the port number is set to 2598.

To modify session reliability port number:

  1. Start Citrix Studio.
  2. Open the Session reliability port number policy.
  3. Edit the port number.
  4. Click OK.

Session reliability timeout

This setting specifies the length of time, in seconds, the session reliability proxy waits for a user to reconnect before allowing the session to be disconnected.

Although you can extend the amount of time a session is kept open, this feature is a convenience and doesn’t prompt the user for reauthentication. The longer a session open, chances increase that a user might leave the device unattended and potentially accessible to unauthorized users.

By default, the timeout is set to 180 seconds, or three minutes.

To change session reliability timeout:

  1. Start Citrix Studio.
  2. Open the Session reliability timeout policy.
  3. Edit the timeout value.
  4. Click OK.
