Flask stops responding to requests after 'max-age' timeout exceeded

[aleksandr-vin]

If you set max-age in response, then flask server unexpectedly stops responding after that timeout.

You can grab this commit aleksandr-vin/turnt-octo-sansa@c6453b5 and run docker-compose up and then try to curl -v http://localhost:5000/ periodically in a loop to find that it stops responding after 40 seconds.

Here is the bash snippet: x=0; while true; do echo $x; curl -sv http://localhost:5000/ ; sleep 10; x=$((x+10)); echo "" ; done
