Redirect outdatedbrowser.com according to language

[Baptistou]

Hello,
I really like outdatedbrowser.com, but by default it is redirected to outdatedbrowser.com/en.
Could you redirect your website according to the HTTP header Accept-Language please ?
For now, I am using the following Apache conf, it would be nice if it was done in your side.
Thank you :)

SetEnvIf Accept-Language (.*) LANG=en
SetEnvIf Accept-Language fr-FR LANG=fr
# ...
RewriteRule (.*) http://outdatedbrowser.com/%{ENV:LANG} [R=302,L]
