Page Route Rewrite/Sanitize without Custom Server

[mengyu-zhang-dev]

I'm running into an issue for supporting a (invalid?) url. I couldn't find any solutions applicable without introducing a custom server. With the removal of documentMiddleware experimental flag, are there any other way to rewrite/sanitize url?

e.g.
https://domain.com/a?foo=bar#test/b/c

rewrite/sanitize into

https://domain.com/a/test/b/c?foo=bar

Thanks in advance!

The solution I used for now is adding index.js into /pages/a

Then use window.location and useRouter to route on client side.
