I'm getting this too, on a URL which is a feed URL, returning RSS. So, yes, there are automated requests to that same URL. They are mostly from FeedBurner, since the public feed URL redirects to it, and then FeedBurner reads a private feed URL that is only for it + testing.
But it shouldn't be checking it very often. It does appear that it checks it approximately once per subscriber per day, rather than caching the value for all subscribers, which is disappointing. But, since I know when the next feed item will be available, I'm setting the TTL precisely so that the feed expires just as the next item becomes available. This should minimize calls to once per day per subscriber. That quantity of usage shouldn't trigger an error like this. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
