Description

https://yaya.yuka.dev/ is running a axum based webserver with a axum::Router. It has a nest route for /public that contains a ServeDir service with path /mnt/public/.

Now, in /mnt/public/, there exists an empty directory /mnt/public/foo.
I request https://yaya.yuka.dev/public/foo
And I get:

< HTTP/2 307 
< location: https://yaya.yuka.dev/foo/

while I would have expected a redirect to https://yaya.yuka.dev/public/foo/

This redirect is created here in ServeDir, and it uses the stripped path instead of the original uri to determine the redirect location.

Unsure how to solve this, but some ideas:

• maybe the StripPrefix middleware and OriginalUri could be moved to tower_http and then tower_http can try to use the OriginalUri first and then fall back to the req.uri().

• Or the nested route service could attempt to rewrite relative redirects, but that seems like it would not generally work since applications behind a reverse proxy could also have other ways of redirecting

• Or ServeDir could be configured with a static prefix that is added to the redirects
