Hi Dev, CORS specification allows caching the preflight response for a certain number of seconds through Access-Control-Max-Age header [1] .
Some browsers have this feature by default which overrides this header if the value specified is greater than their value[2] Firefox - 24 hours Chrome - 10 minutes Chromium - 5 seconds Mathieu(https://github.com/mathieu-pousse) has sent a PR though [3]. Please review and provide feedback.
