Session Resume provides end users with the ability to resume a disconnected or interrupted Silo session, for up to 30 minutes from the time of interruption.  

Technical Requirements

When Silo loses network connectivity, Session Resume will display information that it is attempting to reconnect to resume the session. There will be multiple connection attempts at a preset interval, until Silo has successfully reconnected, or when the time limit has been reached.  


Session Resume is Enabled by default, and requires no additional configuration. However, customers can employ Windows Registry changes to modify Session Resume re-connection options, as well as, disable Session Resume via the Silo Admin Console Policy. These registry settings are discussed below:


1.  A Windows or macOS installation of Silo, or Silo Web Client

2.  Silo version 2.9.12 or later for Windows; or Silo version 2.9.10 or later for macOS must must be installed

User Interface (UI) Experience 

The UI experience is limited to informational pop-up windows detailing the Silo disconnection and re-connection process.


The first informational pop-up window is generated as soon as Silo detects an interruption and begins the initial attempt at re-connection.


If the initial re-connection attempt is not successful, Silo will continue to reconnect on a preset interval, with a second informational pop-up window being displayed, prior to each re-connection attempt, to highlight the process.


Note: Please see the Session Resume Registry Entries section below for details on how to set the frequency for connection attempts.

Admin Console Configuration

Session Resume can be disabled/re-enabled from the Session Resume policy page.


From the Silo Admin Console navigate to the Session Resume policy page.
