I've noticed quite often after several days of no traffic that my basic Flask app seems to require a "wake-up" request before the app will respond. I have a basic GET URL that functions as a simple ping, and I often need to hit that twice (usually just a curl from the shell) before my POST URL will function properly. The first GET request simply returns nothing (not even an error). The second one returns the hard-coded string, after which the POST works.
Any suggestions?
