An animated client-server request lifecycle: DNS lookup, TLS handshake, HTTP request, server processing across web/app/database tiers, and the cached response path back to the browser.

Computer Science3DAdvanced60 FPS

A browser sends a request across the internet to a server and back — this scene animates that whole pipeline: DNS lookup, TLS handshake, CDN edge caching, and the web/app/database tiers that produce a response.

🔬 What It Demonstrates

Glowing packets trace the real hops of an HTTP request: name resolution, a secure handshake, the request itself, backend processing across tiers, and the response path — with a CDN cache hit shown as a dramatically shorter shortcut.

🎮 How to Use

Adjust network latency, switch between HTTP and HTTPS, choose GET or POST, and toggle CDN caching. Press "Send request" (or let it auto-fire) and watch the round-trip time and path update live.

💡 Did You Know?

A cache hit at the CDN edge can be an order of magnitude faster than a full round trip to an origin server and database — which is why caching is one of the highest-leverage tools in web performance engineering.
