Rewrite * except wp-login.php to /wp-admin{uri}

[Schaukelstuhl]

1. The problem I’m having:

I want to rewrite every request to /wp-admin{uri} except /wp-login.php.

2. What I tried & What i get

I used this Caddyfile:

wordpress.example.com {
    reverse_proxy :8001

    @wp-login not file wp-login.php
    rewrite @wp-login /wp-admin{uri}
}

And requested “wordpress.example.com/wp-login.php”.

But I get “404 Not found” from my apache webserver behind the caddy reverse proxy. And in the apache logs shows requests to “/wp-admin/wp-login.php”

3. Caddy version:

v2.7.4

4. How I installed and ran Caddy:

a. System environment:

x86_64, Podman with official Caddy docker-image

b. Command:

podman run --detach --network host \
    --volume /home/root/caddy/config/:/config/ \
    --volume /home/root/caddy/data/:/data/ \
    --volume /home/root/caddy/Caddyfile:/etc/caddy/Caddyfile \
    caddy:latest

5. Links to relevant resources:

Solved.

wordpress.example.com {
    reverse_proxy :8001

    @wp-login not path /wp-login.php
    rewrite @wp-login /wp-admin{uri}
}

Used path anstead of file. I did not fully understood the usage of file matcher.

Yep

The file matcher is for checking if a particular file exists on disk, usually paired with a placeholder as input.

The path matcher is the correct thing to use to have a condition on the request path itself.
