There's a web page that updates once in a while and I would very like to be notified when it is updated, preferably using some sort of feed (such as RSS). Unfortunately, that website itself does not publish any sort of feed for that page.
Is there any service which can provide a feed to an external website? E.g. something that will occasionally probe a specific webpage and if it has changed from the last time, publish a new entry in a dedicated feed.
