Hi,
I have a simple form that dumps selected answers to XML file. How to prevent anonymous user from submitting this form many times?
I am not looking for totally bulletproof solution, and I have a limitation that I cannot use the database, and therefore no SqlMembershipProvider.
Will some cookie checking work? How to do this right?
Thank you in advance.
Update: To be more precise, I do not only mean some accidental submitting of the form but to prevent user that visited the site a week ago from submitting this form again.
