Myra CDN, based in Germany. CDNs need to temp decrypt https traffic, potentially creating a gap in GDPR (and DSA?) compliance. Unless the CDN provider can be shown to be part of the compliance chain. Thus select one that ensures this / is based inside the EU.

You'll notice that for the app/routes/jokes/$jokeId.tsx route in addition to Cache-Control we've also set Vary header to Cookie. This is because we're returning something that's specific to the user who is logged in. So we want the cache to associated to that particular Cookie value and not shared with different users, so the browser and CDN will not deliver the cached value if the cookie is different from the cached response's cookie.

Edge computing is an emerging new trend in cloud data storage that improves how we access and process data online. Businesses dealing with high-frequency transactions like banks, social media companies, and online gaming operators may benefit from edge computing.

The CSS automatically gets injected into <head> with the CDN (tippy-bundle). With CSP enabled, you may need to separately link dist/tippy.css and use dist/tippy.umd.min.js instead.

Because Jamstack projects don’t rely on server-side code, they can be distributed instead of living on a single server. Serving directly from a CDN unlocks speeds and performance that can’t be beat. The more of your app you can push to the edge, the better the user experience.
