The scenario is, If the user has logged in for the first using his one time password it should get redirected to ResetPassword.aspx
If the user is not new, then should get redirected to Main.aspx page.
Should I use IsPostBack or Membership.ValidateUser?
How do we usually code in c# to check if its a new user (using first time login)
I am a newbie to programming not getting enough info on net. Please help
