Your code says exactly that this should happen. After the first request the remember POST parameter will not be set anymore and thus the if-statement evaluates to true . It then will delete the first cookie.
Next time it will delete the second, because the first already doesn't exist anymore.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
