[Serusers] How does $f.did work?

[x-ser at sidell.org]

In ser-oob.cfg, the route[AUTHENTICATION] function has this code:


  # Requests from non-local to local domains should be permitted.
  # Remove this if you want a walled garden.
  if (!$f.did) {
	break;
  }


I'm guessing that the code is permitting all invites that are
addressed to a local destination, regardless of the source of the
invite, so that the source is not required to authenticate itself.  Is
that right?

Also, what is the tersely named $f variable, how does it get
initialized, and what is the meaning of the .did member?

Many thanks!
