Beginning with version v20.06.00 of the main Submitty repository, we have added a new WebSocket interface. Future Submitty releases will leverage WebSockets for dynamic content on frequently changing pages including the TA grading interfaces, discussion forum, and office hour queue without a manual page refresh. To enable WebSockets, you will need to add the following lines to your apache site configuration file for Submitty:

1. Go to /etc/apache2/sites-available

2. Find the appropriate .conf file.

   Note: If you have multiple files, you can double check which configurations are linked (and thus in-use) from the /etc/apache2/sites-enabled directory.

3. Make the modification below somewhere in the file under the top-level VirtualHost directive.

        ProxyPass "/ws"  "ws://127.0.0.1:41983/"
   

   For an example of placement, see our example apache conf file.

4. Restart apache: systemctl restart apache2

5. Install the new Submitty software:

    /usr/local/submitty/.setup/INSTALL_SUBMITTY.sh
   

6. Enable the websocket server systemd unit so that it automatically starts on restarts of the server:

    systemctl enable submitty_websocket_server
   

7. Start the WebSocket daemon:

    systemctl start submitty_websocket_server
   

8. Verify that the daemon is running:

    systemctl status submitty_websocket_server
