Worker mode not working as expected

[come-nc]

What happened?

Hello,

I am trying to use worker mode for a few endpoints (see nextcloud/server#61115).
Looking at metrics, it looked like worker mode was only used for one of them, index.php, but not remote.php.
I wondered whether the match was needed so I added match index.php/* and match remote.php/* to the workers.
First surprise was that this doubles the number of workers, because I now have index.php and index.php_0 listed and same for remote.php.

So I am not sure whether this is needed and how it should actually be configured. The documentation shows worker configuration without any match and does not state whether that limits it to direct hit (/index.php) and how to extend it to all subpaths targeting this endpoint.
This is hard to debug also because I’m unsure how I could detect whether a request goes through worker mode or is wired outside of it?

Current Caddyfile I’m testing with:

{
        metrics
        frankenphp {
                num_threads 192
                max_threads 256
                max_requests 500
                php_ini memory_limit 512M
        }
}

localhost:81 {
        php_server {
                worker {
                        file index.php
                        num 32
                        watch
                        match /index.php/*
                }
                worker {
                        file remote.php
                        num 16
                        watch
                        match /remote.php/*
                }
                worker {
                        file ocs/v1.php
                        num 16
                        watch
                        match /ocs/v1/.php/*
                }
                worker {
                        file ocs/v2.php
                        num 16
                        watch
                }
        }

        log {
                level ERROR
                output stderr
        }

        }
        respond @forbidden 404
}

I’m also interested in general advices about how to setup/structure the Caddyfile by the way ^^

How do I get that not in html?
I tried franken php-cli phpinfo.php and it still output html.
That’s a huge chunk of text I’m not sure what to censor in. Please provide easier information how to get it in the issue template.
