No any logic for trailingSlash: true

[fejmek]

Description

I looked through the entire application code and i haven't found any logic that would take into account that the application has option trailingSlashes set to true, when redirecting to the appropriate translated urls.

It makes no sense to create additional redirections and it is a big problem when we look at SEO.

I hope I have provided all the information you need

Also this package handle http response header link without adding trailing slash...

EDIT:
Oh, just now i saw the umbrella thread, where this issue is listed. There is any possible chance to deploy this change in this week, SEO scan just punched our applications because of this, just before going into production

Hey @fejmek, thanks for the report! There was some previous discussion about this in #668.

I just had another look and I think there might not be too much missing for this. I've just set up a test suite and will have a closer look if we could address this is in a timely manner.

I'm looking into sharing a pre-release version with you as soon as my test suite is green. I'll be in touch again tomorrow!

@fejmek A pre-release is available as next-intl@3.15.6-canary.0 that supports trailingSlash: true now.

Mind giving it a go in your app? 🙂
