hello. i am trying to get started with PuSH and the public hub and ran into some issues. i started from the PHP code and finally was able to make the callback work, so that i see the hub making the challenge request to the callback. after that, i see my status as subscribed. however, when i go to https://pubsubhubbub.appspot.com/subscribe and want to see the subscription, i get the message that it does not exist. regardless of that, it does exist, because i do get POST notifications to my callback. the real problem is that all these notification messages seem to be empty (reported as having content-length "-" in my apache access log). i do get the POSTs when i am updating the feeds i am subscribed to, but i don't get any content. any idea what might be going on?
thanks! dret.
