Vlad, in the book:
http://www.web2py.com/books/default/chapter/29/04/the-core#HTTP-and-redirect
And i can comment out +/- the code:
def user():
# just a way to ensure form allways have a value
form = CAT()
try:
# the call to auth can return a lot of things
# it can be a form (a login form for example or a registration form)
# it can raise a redirect - for exple if the login is correct
# it can be the login form with erros if the password is incorrect
# etc
form = auth()
except HTTP as e:
if e.status == 303'login' in request.args:
if ('login' in request.args) and auth.user:
# probably a success, the user has logged in
do_your_loging_event_here()
# ensuere u do the redirect, for example a raise shoul do it
elif 'logout' if request.args:
do_your_logout_event_here()
# give the form to the view, can be register form, login form, etc
return dict(form=form)
