[00:00:00]You open instagram.com. Your phone thinks it's talking to Instagram. It's actually talking to Cloudflare.

[00:00:06]Instagram has no idea who you are.

[00:00:08]That's a proxy. It's a middleman that handles your conversation. The word covers two opposite jobs. A forward proxy sits in front of you. It carries your request out. Your office uses one to block Facebook. Your VPN uses one to hide your location. A reverse proxy sits in front of the server. Cloudflare and Nginx are the famous ones. They hide what's behind. Your app might be one server or a thousand. The client never knows. Here's the trick. It's not where the proxy sits. It's who it hides.
