Hi list, Hello. I'm generally not a member of lists of this kind - am mostly a user of the kind of stuff you guys develop!
Not being in the same league as most of the folks on this list, I have a few questions to ask. If you think this is not the appropriate place to ask just tell me and I'll go away. The page http://pubsubhubbub.appspot.com/subscribe has new subscription creation form and the questions are related to the form. (me = the subscriber) Callback - is the url that the hub will try to access when it find that there's some new content. Topic is the feed url - which means that whenever there is new stuff in the feed, the callback url gets hit. The question is: What prevents a feed publisher from drowning the hub or me (the subscriber) with multiple updates - maybe thousands per second? (In real life, such things happen, you know - at least in my life they do :) ) Can the subscriber set a limit to the number of callbacks it wants to receive in a time frame? Or any other way that may have been thought of of "solve" this problem. Basically I'm a little uncomfortable with losing control over when to ping - but am still interested because of the enormous band width and cpu savings of course. Question 2. Verify type - Synchronous/asynchronous - what verification is this? I tried to look for documentation but couldn't find any. Maybe I was looking at the wrong places so any pointers would be appreciated. Yes, the code would tell me, but currently am trying to use this as a "user". Question 3. Verify token - what is this for? Is it the same verify as "Verify type" above? Question 4. HMAC secret - being optional, what does a subscriber stand to lose if it's not specified? Many thanks in advance. Alok
