You may use a -t if you like, but there is a default value if you don't.

You should not use -a, see the text after the -a option for a
description of how the helper works when you don't use -a.

        "Without this flag the helper automatically starts the

What I tried to tell you was to read the man page text after the -a
option, explaining how the helper operates when not using -a (i.e. what
is the default mode of operation).

You may use the active mode if you like, but it's somewhat more
complicated to use. It's meant for situations where user must actively
accept a terms-of-use page or similar before they are allowed to browse.

And the example has not been removed. It's 3.0.PRE5 which is not yet
updated.

Arguments is sent via the acl directive.

A session identifier is whatever you send to the helper. Could be any of
the above, as per your external_acl_type definition.

It's no flow in such sense. It's just a definition of what identifies a
session in external_acl_type, and then the helper monitoring the
activity of the session and timing out the session when idle (or
alternatively explicit login/logout actions when using the -a option).
