Summary

An origin trial for Signed HTTP Exchanges (or SXG) started in Chrome 71 and is scheduled to end in the same release, Chrome 71.


We initially set this period relatively short to manage risks, but now that 71 hits stable and it looks the feature is working stably, we want to extend the period so that 1) we can collect more feedback and data, 2) the sites that are running this trial don’t need to shut down the trial (ideally until it just ships), and 3) other sites that are currently considering origin-trial can have more chances to join.


More information can be found on the previous intent to experiment thread:

Experimental timeline

Currently it is configured so that it’s enabled for Chrome 71 and set to end.  We want to extend this to also run for Chrome 72, ending Mar 12.


  • Chrome 71 <--- This is the one currently enabled

  • Chrome 72 (Branch already cut, Stable on Jan 29 til Mar 12)

(We may want to an extension one more time depending on when we decide to ship, let us know if requesting for a trial extension multiple times could have any problems. Thanks!)
