CloudFlare aims to make the internet more secure by encouraging websites to adopt HTTPS, a protocol that encrypts data sent between web servers and users' browsers. However, many sites still suffer from "mixed content" issues where some elements are served over insecure HTTP connections, compromising overall security. Fixing this problem can be challenging due to the complexity of modern websites and the need for all subresources to be served over HTTPS. CloudFlare has introduced a new feature called Automatic HTTPS Rewrites that automatically upgrades http:// URIs to https:// if they are known to be capable of using HTTPS, making it easier for website owners to transition their sites to full HTTPS.
