How to redirect uppercase url and trailing slash?

Question

Nginx

What is the simplest and most efficient redirect solution for this

http://example.com/hello/
http://example.com/HELLO/
http://example.com/HELLO
http://example.com/HeLlo
и тд...

After some digging I didn't find a
http://example.com/hello
simple solution, only perl or lua scripts.
1. is there an example of such a working proven script
2. which is more efficient - pearl or lua?
3. Is there a significant drop in performance?

Answer 1

Why only on perl or lua - does locationn't it work?

location ~* ^/hello/$ {
    return 302 /hello;
}

The code has not been tested, but it seems to me that it should work, there is nothing esoteric here.

The first line in Google works, I personally use it on pearl, it redirects very quickly.
