When SlowAPI.com launches a few weeks ago, I had 301 redirects but this is cached indefinitely by Chrome Browser. To fix this, you can F12 (or Ctrl+Shift+I) to open the dev console, and type in the following:
fetch(‘https://slowapi.com’, {method: ‘post’}).then(() => {})
That will send a post request to invalidate the 301 cache.
