Hello Oiwasan,

Thank you for your response, and look forward to reading the next revision.

As for that uncompleted thought; my apologies, it should not have been
included!  When I had started that thought, I had not yet finished all
of section 5.  I think, for an experiment, the interaction of
webform/cookie authentication with this extension is covered as well as
can be done until the experiment is performed.


Thanks ,
