Client-side caching is a key technique to improving front-end speed and user experience. Whilst it may appear complex and risky, investing the time to review your content and setting the correct response headers will reduce bandwidth utilisation and improve speed for return visitors as well as mid-session.

   TIL: #Cloudflare doesn't support the Vary HTTP header, which means the origin server can't do any content negotiation, for example send WebP or AVIF for a JPEG request…

   #Fastly supports it, just saying… 😅

   @bagder hi Daniel, reading https://daniel.haxx.se/blog/2016/08/18/http2-connection-coalescing/ (yes, I'm late 😅)

   If DNS B.example.com returns 192.168.0.2 and 192.168.0.3, is TLS really enough to be sure it also works on 192.168.0.1?

   BTW, there's a typo near the end: "both IPv4 and IPv4 addresses".
