HTTP3 on theguardian.com

Open jamesgorrie opened this issue 3 years ago • 0 comments

  • Turn on http3 on code to see it all works.

  • Can we get a number on how many people already support HTTP3? https://developer.fastly.com/reference/vcl/variables/client-connection/fastly-info-is-h3/

  • If we want to turn this into a n% test how do we do this at a VCL level?

Ways to A/B test

  • Change assetsUrl based on test in frontend.

  • ~Can we make assets.guim.co.uk/i.guim.co.uk over HTTP3 fully without a negative impact on performance~ This is probably not as good as the above option.
