Language-based redirect only works when 1 browser language set

I noticed language-based redirects aren’t working of the browser has two languages configured.

I have a redirect rule in my _redirects file as follows:

/  /jp   302  Language=ja

I have set my browser to Japanese with English (US) as my secondary language. My browser (Chrome) sends the following request header.

accept-language: ja,en-US;q=0.9,en;q=0.8

This does not redirect the site.

If I change my browser to Japanese only it sends the following header:

accept-language: ja

When I retry it redirects fine. I have no specific rules set up for English, which is why I’m surprised the redirect doesn’t work. I’m pretty sure this used to work. Can someone clarify?


Hi, @cbetta_box, welcome to our community site. As I believe you may already be aware (via other communication outside of this community thread), this is a known issue we are tracking at this time.

We’ll update this ticket if/when those issues are known to be resolved (and we’ll also email you directly relating to the other communication channel as well).

Any updates on this issue? We use Netlify as our main redirect system.

The response I received via email was that this was a known issue that is in the process of receiving a wider rewrite that might take till Q2 next year. Not ideal, but excited for the improvements.

@jesse-deboer, I don’t have an official ETA of if/when this issue will be resolved.

Sorry to ping, but any updates here? Or ideas for a temporary workaround when the browser sends multiple languages?
