Drupal - Call Function from Link but don't create new page?

I don't understand about the HTML's header thing, but the basic idea here is to change the header, and follows a file for the user to download.

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.
