Reconnecting when the server is restarted

I have 2 documents open on 2 separate tabs. I kill the node server and then start it again. When I type in one of the tabs, the changes are no longer reflected in the other tab. I tried this on the hello-ace and the textarea examples.

Is there a way to get the clients to try reconnecting to the server periodically? Otherwise, everytime I deploy the app, users who are currently collaborating on a doc will be affected.
