CloudFlare Now Supports WebSockets

Cloudflare now supports WebSockets, a protocol that enables real-time communication between web servers and clients. This feature was requested by many users and is initially being rolled out to Enterprise customers, with plans to extend support to all Business and Pro customers in the coming months. The adoption of WebSockets presents new challenges for Cloudflare's network stack due to its long-lived connections compared to traditional HTTP requests. To overcome these challenges, Cloudflare has made changes to its connection counts and port reuse settings, allowing more concurrent connections per server.
