Thanks Anthony for reply! I used session=None because SQLFORM was not
working on disabling browser cookies.
Why can't you use cookies?
Currently I am using session and cookies, but I am worried about the users
who disable/block their browser cookies (don't know % of such users).
I disabled my browser cookies from browser settings, then I am not able to
submit form successfully. So how can I make my web2py application(/SQLFORM)
to work for users who disable their browser cookies?
SQLFORM will not work if browser cookies are disabled?
Thank You
