Hello! i am experimenting with pubsubhubbub, and i cannot understand how Content Destribution works I am following the draft at http://pubsubhubbub.googlecode.com/svn/trunk/pubsubhubbub-core-0.3.html#contentdistribution but there are not many details about content destribution.
I understand that the hub has to notify each subscriber for this topic. Ok. The notification is a POST request to the callback URL of the subscriber. What will the request be like? the feed's new content will be on the request's body? If yes, then how will the subscriber understand for which topic the new feed entry is about? Does there need to be a header entry about the topic URL maybe? Thank you!
