How come $_SERVER['HTTP_REFERER'] is blank?

Not all browsers set this, and the HTTP/1.1 spec says it should only be set when the referer is a link (as opposed to someone typing the url into the address line). See http://www.php-faq.com/httpheaders.php#14.36 17. More.

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.
