# EgoCX CDN · Content Delivery Network

**cdn.ego.cx** is the official content delivery network (CDN) of **EgoCX**, designed to accelerate the loading of static assets, multimedia, and data across the entire digital ecosystem of the brand.

This CDN is not just technical infrastructure: it is a **strategic SEO asset** that boosts the ranking of the root domain [`ego.cx`](https://ego.cx/) by:

- **Reducing latency** and improving **load speed** (Core Web Vitals).
- **Geographically distributing** assets, bringing content closer to users worldwide.
- **Offloading the origin server**, allowing `ego.cx` to respond faster to dynamic requests.
- **Optimised cache structure** per resource type, maximising efficiency and cache hit ratios.

## 📂 Directory structure

The CDN organises its resources into three main families, each with specific caching policies and headers:

| Path | Usage | Cache |
|------|-------|-------|
| `/assets/` | Compiled code (CSS, JS, fonts, SVG icons) | `max-age=31536000, immutable` |
| `/media/` | Heavy content (images, videos, 3D models) | `max-age=86400, stale-while-revalidate=43200` |
| `/data/` | Logical and sensitive files (documents, AI configs) | `no-cache, must-revalidate` |
