Summary of Changes
Vary: Content-Encoding
must always be set, even if the client doesn't support compression, to prevent corruption of intermediate caches such as Varnish.This bug has been reported by @nicolas-grekas while working with Vulcain.rocks. Fun fact: Nicolas reported the exact same bug to PHP... 12 years ago 🙂
