What is simplest way to convert Request-URI to lowercase?

[alcina]

Hello,

We are using nginx heavily. We need to rewrite all request URIs
into lowercase, e.g,

http://foo.bar/ThiS_will_be_Rewritten/?q=Foobar

will be translated into

http://foo.bar/this_will_be_rewritten/?q=foobar

I know some modules (Perl, Lua) can do this. My question is
what the simplest way (module) to do that, because Perl/Lua
seems to be overkill here

Thank you very much.

Why?

Depending on the answer, it may be more appropriate for your back-end
processor to do the conversion instead of nginx.

(Note: this isn’t “please justify your needs”; this is “have you
considered the possible alternatives”.)

If it turns out that nginx is the correct place to do this conversion,
then…

The simplest module is the one that you (arrange to) write that does
exactly what you want and no more.

There doesn’t appear to be a default-distributed module that does that.

You may be able to use or adapt the module named “Lower Upper Case”
listed at NGINX 3rd Party Modules | NGINX to do what you want.

There are the general-purpose embedded language modules that you could
use – you have to decide whether the run-time “overkill” overhead
is more important that your build-time overhead to get the dedicated
module written.
