[web2py] detect user login

[Richard Vézina]

Hello

I need to have a response.flash on index page at login but not when the user
come back on index page during a session. I try to user session.counter but
the session is not reset until the cookies are erase I think.

Here my index controller (*not working*) :

def index():
    """
    Index page
    """
    session.counter = (session.counter or 0) + 1
    if auth.user and auth.user.first_name!=0 and session.counter<=0:
        response.flash = DIV(T('Hello ')+str(auth.user and
auth.user.first_name),BR(),T('Welcome on the '),appTitle)
    elif session.counter>0:
        pass
    else:
        response.flash = T('Hello')
    return dict(message=T(''))
