Set no-cache and expire in the past. I am guessing the Google Edge cached the page and the request. (just a theory)

I had a weird anomaly this afternoon. We have an app that is been online for a few months now. It has a view that accepts get requests and the same view accepts post requests. This is the common web form pattern. The user goes to this view (get) and they fill out the form and submit (post). Successful post redirects to a different view. Errors are shown to the user on the same view with the form. This normally works great. This afternoon, we noticed a really weird thing. When we would go to this view, it would treat it like a post - with previously posted data in the form. So imagine, it was as if we had just posted, but of course we had not. In fact we had not even entered data. The data was from some other user. Here are some pertinent characteristics of the app; and this incident. It uses the Python stack, using the webapp framework with some extensions. We are not doing anything tricky with those post parameters. Standard processing - no caching of them or explicit thread local. The app was getting hit on average about 5 times a second at the time (not all that traffic was to this view) - this number according to the dashboard. This hit profile was/is not a spike. The system can average that during US waking hours fairly routinely. At the same time that this weird post situation was occurring, we could not update the app using appcfg. At nearly the same instant, as best we can tell, the update started working and our weird post thing went away. The logs showed no errors of interest either during or after this condition. I'm posting to see if anyone else may have seen something similar before or have any ideas about further ways to research it. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
