The newer versions of the live feed and event views use Ajax to request information from the server and populate the views dynamically. This option allows you to specify a timeout if required after which requests are abandoned. A timeout may be necessary if requests would overwise hang such as on a slow connection. This would tend to consume a lot of browser memory and make the interface unresponsive. Ordinarily no requests should timeout so this setting should be set to a value greater than the slowest expected response. This value is in milliseconds but if set to zero then no timeout will be used.
