Language redirect only working in Safari

I added the following to my _redirects file to redirect user with french language set as prefered in their browser to the French homepage:

/ /fr 302  Language=fr,fr-fr,fr-ca

It does work on Safari, but not on Chrome or Firefox. Anything I’m doing wrong?

Hi @regisphilibert,

I just tested from the latest version of Chrome and the redirect is working for me:

Can you copy the full request you were sending so I can see what the differences were?
