Need only to change links from https to http to access files with no SSL?

That's usually how it works, but it depends on your specific webserver's setup. For example, you can configure a web server to disallow non-HTTPS traffic completely or you can even serve totally different content between HTTP and HTTPS.

Yes, using https: or http: in your URLs controls whether the access is secure or not.

You can force the use of the SSL site for non-https URLs. This way people cannot access the pages without encrypting the communication In the http virtual host, VirtualHost 192.168.0.4:80, put just the line -- 88.

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.
