Subdir reverse_proxy fails while subdomain reverse_proxy works perfectly

[ske5074 (SeanK)]

1. Output of caddy version:

2.5.2

2. How I run Caddy:

caddy start

a. System environment:

5.15.63-0-lts #1-Alpine SMP Mon, 29 Aug 2022 07:17:28 +0000 x86_64 Linux

b. Command:

caddy start

c. Service/unit/compose file:

NA

d. My complete Caddy config:

wp.home.arpa {
        encode gzip
        reverse_proxy localhost:8080
        file_server
        @disallowed {
               path /xmlrpc.php
               path *.sql
               #path /wp-content/uploads/*.php
        }
        rewrite @disallowed '/index.php'
        reverse_proxy /xr/* 127.0.0.1:3000
}
xr.home.arpa {
        @blocked not remote_ip 10.0.0.1/24
        respond @blocked "<h1>Access Denied</h1>" 403
        reverse_proxy 127.0.0.1:3000
}

3. The problem I’m having:

While xr.home.arpa works brilliantly, wp.home.arpa/xr/ fails, showing:
Cannot GET /mc/

4. Error messages and/or full log output:

No errors,  just does not work.

5. What I already tried:

I tried using handle, handle_path, route, had to learn about without not working… I can easily do this in traefik (which is crazy since I moved to caddy to to traefik breaking from being so complex)

6. Links to relevant resources:

See this article, which explains:

The "subfolder problem", OR, "why can't I reverse proxy my app into a subfolder?"

Have you ever tried to reverse proxy an app into its own little subfolder of your domain name? Makes things neat, doesn’t it? Using example.com/foo/ for one app, example.com/bar/ for another. If you’re coming here from one of the selfhosted communities, you might be thinking along the lines of example.com/sonarr/, example.com/radarr/ etc. Chances are, you’ve tried some configuration along these lines: example.com { redir /sonarr /sonarr/ handle_path /sonarr/* { reverse_proxy localhost…

Thank you for the article. It certainly explains the issue. It looks like subdomains are the way to go, as the advanced option looks much more difficult. Thank you @francislavoie !
