The WMS protocol has this covered with an update sequence number, clients are expected to poll this value when connecting to the service to see if any cached layer definitions they are working from have changed.
As for the contents geoserver has had an RSS feed that can be used to keep track of any changes made via WFS. - Initially used to keep a cluster of WFS's in sync it could be used by clients also. - The same hook is used to automatically truncate any tiles that have been modified via WFS (so if your tile caching settings are set appropriately downstream caches should pick up any changes as their contents are refreshed) The difficult part of you question is "automatically refreshing the URL" - the URL remains the same in each case as it is the same data service, and data product being published. The contents of the data have changed but the service that accesses it remains available via the same URL.
