Have I covered all bases with security when echo'ing a server variable to the page?

Use htmlspecialchars instead of strip_tags .

If you want to reference the same schema/host/path a simple action="?" schould suffice. According to http://tools.ietf.org/html/rfc3986#section-4.2.

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.
