When a site goes offline, connections to this site will be forced closed. Those connections will reconnect, as long as the site stays offline, they will be connected to remote site.
You can now enable an option so that when the site comes back online, the connector will disconnect all these connections that couldn't get to their preferred site so that they will then reconnect to the expected site with the appropriate affinity.
When not enabled, connections will continue to use the server originally configured until they disconnect through normal attribution. This is the default option.
