Caddy - strip trailing slash

If you’re using the Caddy (v2) server and want to remove a trailing slash from URLs (as on this blog), use redir

example.com {
  root * /srv/example.com
  encode zstd gzip
  header {
    Cache-Control max-age=3600
  }

  @noSlash path_regexp trailingSlash ^(.+)/$
  redir @noSlash {re.trailingSlash.1} 301

  // ...
}
