The following rule in my _redirects file:
/de/über-uns /de/about-us 200!
works locally when using netlify dev but not when deployed to production.
https://startsteps-next.netlify.app/de/über-uns
Other rewrite rules work perfectly.
A 200 is a rewrite, not a redirect, it will return the content but not change the URL in the browser address bar. If you wish to change the URL, you need to use either a 301 or 302. Refer to the HTTP status code documentation.
Sorry I wrote it badly, I meant rewrite.
Changing the rewrite rule to
/de/%C3%BCber-uns /de/about-us 200!
Makes it work in production, but not with netlify dev.
In either case, when I visit /de/über-uns and /de/about-us I see the same thing. This is what you are wanting to achieve? Or is the issue that you can’t do it when using Netlify CLI?
Yes /de/über-uns and /de/about-us should show the exact same thing (which it now does as I have managed to find a workaround shown below).
The problem is that this rule:
/de/über-uns /de/about-us 200!
Only works with netlify dev and not in production.
And this rule:
/de/%C3%BCber-uns /de/about-us 200!
only works in production but not with netlify dev.
This is not something I have noticed before (probably because I generally use English) but I have replicated it. I notice there is nothing in the documentation about this as a limitation though.
Based on posts in Diacritics in redirects encoding characters such as ü is the accepted way of doing it. The fact this works differently using Netlify CLI is possibly a bug. You may wish to file an issue on the CLI repository.
