Describe the Bug

When accessing sunshine on localhost everything works fine. But when you try to use a reverse proxy like Caddy the content won't load how it should.

The server will show that the header type for the CSS content is text/plain rather than text/css.

Expected Behavior

The page should look normally without any issue on it's end:

Additional Context

Setting the Caddyfile to catch all *.css files and forcing the content-type fixes the issue:

sunshine.localhost {
        @css path *.css
        header @css Content-Type text/css

        reverse_proxy localhost:47990 {
                transport http {
                      tls_insecure_skip_verify
                }
        }
}
