help needed with httpd.conf and rewrite directive

[Kevin]

Hey gang,

I'm trying to setup some rewrites in httpd that are needed to make some
software we just purchased work.

The vendor's official docs only support nginx and apache, and I'm having a
helluva time understanding how to make them work in our beloved OpenBSD.

Below is the nginx sample they provide.

Anyone with some httpd rewrite foo mind whacking me with a clue stick on
how to accomplish this purty please?

Thanks,
Kevin

   location /sendy/l/ {
        rewrite ^/sendy/l/([a-zA-Z0-9/]+)$ /sendy/l.php?i=$1 last;
    }
