Note from 15 March 2022

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… 😅

  1. I still don't understand why using Cloudflare in front of Netlify allows for a much better and stable Time To First Byte (TTFB) than Cloudflare Pages or Netlify alone… 🤷‍♂️

    SpeedCurve graph with Time To First Byte for the 3 hosting solutions

    TTFB for static sites should always be very low.
