Ever updated your website only to find your changes don’t show up? That’s caching in action — and it can speed up your site or totally wreck your user experience if you don’t manage it right.

In this episode, Charly explains caching from the ground up, covering browser, server, CDN, and even ISP-level caching. Learn how it works, where it can go wrong, and what you need to do to avoid the biggest pitfalls.

📌 In this episode:

✅ What caching actually is — and why it matters

✅ Different types: browser, server, CDN, ISP

✅ Why outdated cache can break sites and confuse users

✅ When caching improves speed and when it makes things worse

🛡️ Why “more caching” isn’t always better — and how to reset everything
