Scenario: A Citrix Administrator is working on a published application. The network is connected for 100 seconds but is interrupted and applications…

The scenario describes the exact functionality of the Session Reliability policy. This feature keeps a user's session active on the Citrix server even when network connectivity is lost. To the user, the application window freezes and becomes unresponsive. Once network connectivity is restored within the configured timeout period (default is 180 seconds), the session automatically resumes at the exact point of interruption without requiring re-authentication. The 100-second interruption described is within this default timeframe, making Session Reliability the enabled policy.

A. Load Management: This policy distributes user sessions across servers to optimize performance and resource utilization; it does not manage session resilience during network interruptions.

C. ICA Keep Alive: This feature sends periodic packets to prevent network devices, like firewalls, from closing connections that appear idle. It does not handle network outages.

D. Auto client reconnect: This policy reconnects users to sessions that have been fully disconnected. Session Reliability prevents the disconnection in the first place by buffering the session on the server.

1. Citrix Virtual Apps and Desktops Product Documentation, "Session reliability".

Section: Session reliability

Content: "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... The default setting for the Session Reliability timeout is 180 seconds." This directly supports the behavior of a frozen screen and automatic resumption within the specified timeframe.

2. Citrix Virtual Apps and Desktops Product Documentation, "Auto client reconnect".

Section: Auto client reconnect

Content: "With Auto client reconnect, Citrix Workspace app can detect unintended disconnections of ICA sessions and reconnect users to the affected sessions automatically... When Session Reliability is enabled, it is the default mechanism to handle reconnects." This clarifies that Session Reliability is the primary feature providing the seamless experience described, while Auto client reconnect handles sessions that are already disconnected.

3. Citrix Virtual Apps and Desktops Product Documentation, "ICA policy settings - Keep-Alive settings".

Section: ICA Keep-Alive timeout

Content: "Enabling this setting prevents broken connections from being disconnected. If Citrix Gateway detects no activity... it disconnects the session. To prevent this disconnection, the keep-alive feature sends packets..." This shows its purpose is to prevent idle timeouts, not to manage active network outages.
