DO it again: how we used Durable Objects to add WebSockets support and authentication to AI Gateway

Cloudflare announces a beta WebSockets API for AI Gateway that provides a single, persistent, authenticated connection to supported AI providers via Durable Objects, reducing connection overhead and simplifying scale. The API supports authentication with `cf-aig-authorization` (and `sec-websocket-protocol` for browsers), reuses Universal Endpoint logic, and introduces `eventId` to correlate concurrent streaming responses. The post includes example code for Node.js and browsers, explains metadata wrapping for responses, and outlines planned support for WebSocket-to-WebSocket provider connections in Q1 2025.
