Support permanent (308) redirects for default locale

[jasperhartong]

If the middleware is configured to use localePrefix: "as-needed", urls are redirect from /:locale/slug to /slug with a 307 Temporary Redirect. From an SEO perspective it might be better to allow these redirects to be performed with a 308 Permanent Redirect.

As far as I can tell the middleware doesn't provide a way to configure this behaviour?

As far as I know, a 307 should be fine: https://webmasters.stackexchange.com/a/123092

Thanks for the swift answer, going to double check it with my SEO consultant.

I think it makes sense that you would want a 307 when using locale detection, but when it comes to the situation described in the original question, I think a 308 is definitely needed.

Any chance to custominze the 3xx status code? My seo experts prefer to have 301 instead

[aleksijohansson]

I would really need this possibility to set the redirect status to 308 as well

Based on #666 the suggested method is to "overwrite the response status code in certain cases if the next-intl middleware returns a redirect".

This is solution is requires you to create a completely new response, since the status of responses is immutable, which is not great.

Hey aleksijohansson ;

if you want to redirect as 308 you can add a basically code your nextjs middleware like below;

export default async function middleware(req: NextRequest) {
const nextUrl = req.nextUrl;
const pathname = nextUrl.pathname;

if (pathname === "/") {
  return NextResponse.redirect(`/${defaultLanguage}`, {
    status: 308,
  });
}
  return intlMiddleware(req);
