RFC 9111 redefines HTTP caching with nuanced Cache-Control directives that govern browser, CDN, and proxy behavior. This technical deep dive unpacks freshness validation, stale responses, and browser refresh mechanics—essential knowledge for optimizing web performance.

When POST requests mysteriously failed inside Amazon VPC while working flawlessly over public internet, Deliveroo engineers uncovered a subtle HTTP header omission in Go's proxy implementation. Their debugging journey reveals critical insights about Content-Length handling, CDN behavior, and cloud networking edge cases.

In an era dominated by OAuth and token‑based schemes, a recent thoughtbot podcast revisits HTTP Basic Auth, dissecting its use cases, strengths, pitfalls, and how it stacks up against modern security methods. The discussion offers developers a clear framework for choosing the right authentication strategy for their applications.

JavaScript’s module import system has morphed from the familiar CommonJS require to a multi‑protocol ecosystem that includes node:, npm:, jsr:, and HTTPS URLs. This article traces the milestones—from Node’s node: protocol to Deno’s HTTP imports, npm: protocol, and the recent jsr: and package.json support—examining how each shift reshaped developer workflows and the broader ecosystem.

A developer has ingeniously extended the dumbproxy forward proxy server to tunnel PPP connections over HTTP/2, blending dial-up era protocols with contemporary web tech for robust firewall bypassing. This setup delivers direct IP forwarding while leveraging TLS encryption, flexible authentication, and censorship resistance. Tech enthusiasts can now run PPP tunnels through remote proxies, achieving impressive speeds in constrained environments.

Google Chrome will soon warn all users by default before accessing insecure HTTP websites, rolling out in 2026 to protect against man-in-the-middle attacks. This shift capitalizes on near-universal HTTPS adoption and marks a pivotal move in browser-enforced security, with phased deployments starting next year for over a billion Enhanced Safe Browsing users.
