Hello, What's the best way for a publisher to decide how many entries to include, when a hub fetches content (section 7.2) in response to notification?
If, for example, the publisher always replies to a feed request by serving the 10 entries with the latest <updated> time, then the hub must fetch at least once per 10 notifications, or it will miss changes. Are there safe assumptions that a publisher can make about the responsiveness of a hub, or ways to determine the hub's responsiveness? Can it safely decide how far back to go based on the hub's request — for example, always send all entries with <updated> greater than or equal to the request's "If-Modified-Since" header? Thanks! — ?!ng
