CDN Caching Strategies: Maximize Performance and Freshness

Mon, 30 Dec 2024 00:00:00 +0900

Introduction

Content Delivery Networks (CDNs) are the backbone of modern web performance. By caching content at edge nodes distributed globally, CDNs dramatically reduce latency and offload traffic from origin servers. However, effective caching is not simply a matter of enabling a CDN and forgetting about it. Striking the right balance between performance — high cache hit rates and low latency — and freshness — minimal staleness and fast invalidation — requires deliberate strategy.

Subresource Integrity: Protecting Your CDN Dependencies

Fri, 20 Dec 2024 00:00:00 +0900

Subresource Integrity (SRI) is a security feature that lets browsers verify that resources fetched from CDNs or third-party origins have not been tampered with. In an era of supply chain attacks — the British Airways Magecart breach, the Polyfill.io compromise, and numerous CDN incidents — SRI provides cryptographic assurance that the resource your page loads is exactly what you intended.

How SRI Works

When you add an integrity attribute to a <script> or <link rel="stylesheet"> tag, the browser computes the hash of the fetched resource and compares it to the attribute value. If they don’t match, the browser refuses to execute or apply the resource.

Cloudflare Setup: Improving Website Security and Performance

Introduction
