Upon registration to become a member of my site a confirmation email will be sent to the member. The email will contain a link to activate the members account. Example:
http://www.abc.com/activate.aspx?id=<memberId>
My question is if the memberId is visible, then a person can use this link over and over again by replacing the memberId. This will then cause many members account to be activated. Therefore how do I prevent this from happening?.
Your help is kindly appreciated.
Thank You.
