Add notification to subscribers that a feed's URL has changed #38

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
SUMMARY:

Right now Subscribers need to detect when a feed's self link changes, the
feed has been redirected to a new location, or the Hub changes. Instead,
the Hub could notify the subscribers when this change occurs with an
explicit message that's easier to parse. Subscribers who care can repull
the original feed, detect the new parameters, and then renew their
subscription in the new location.

RELEVANT SECTION:  6.2

COMMENT/REQUEST:

More background info is in this wiki document:

Perhaps we could implement this simply as another subscriber verification
request. In the case the feed URL has changed, we can use "hub.mode" as
"changed", and include the new topic URL in the request. In the case the
Hub has changed, we can use "hub.mode" as "moved".
