Now I am confused. You mean having the forum completely separated from joomla? Of course this is possible but then I have to heavily modify the SMF-theme in order to not only show a header similar to joomla template but also insert at least some horizontal menu like in the joomla template. This is the solution one can see on
www.joomla.org, isnīt it? One of the disadvantages is that I have a vertical menu on the left side of my site. This menu would not be visible on the forum site unless I would change it always manually when I changed it in joomla.
My thought was, that it should be easy to exclude this simultaneous login when using the bridge. Isnīt it just a question of cookie modification? Or could the bridge possibly be stripped down to just integrate SMF visually like it does now but without any syncing of the users and fusion of the login cookie?
Anyway, this is more of a bridging problem and not one of the Caching component. Therefore I should ask the bridge author instead of wasting your time here.
