I've hit another obstacle using *session.forget(response)...* In the same controller / function where I'm using this session.forget(response) for the progress bar (ajax) to work properly, I cannot use any session variables (since these are "forgotten" as per the command above) ?!
Is there a way to tell web2py to start "remembering" sessions again, *after* I'm done with the progress bar (the lengthy process has finished, there's no more need for the progress bar) - and now I'd like to use the global nature of the session variables to pass data to other controllers. Any ideas ?
