I'm using:

ScratchDefault mv_no_session 1

in catalog.cfg.

I'd love to get something cleared up.  There seems to be some
confusion about mv_no_session_id and mv_no_session.

First of all, what does mv_no_session_id do?  It does not remove the
session id from the URL as its name implies.  I can verify this myself
and here's a post describing the problem:


Secondly, what does mv_no_session do?  I think it simply removes the
session id from the URL to put the session burden completely on the
session cookie.  Jon, here's a post of your's, to me, recommending
mv_no_session for this purpose:


[set] variables should still persist from page to page with
mv_no_session, but they didn't for me until now.  After working on
this all morning I narrowed the culprit down to [set-cookie] when it
is used with a bad expire date.  I think this is a bug so I'm going to
post a new thread about it.
