Setting a Php $_SERVER value ($_SERVER['something']) using Apache .htaccess

Question

Is it possible using .htaccess or other apache powers to set a custom server value in the php array $_SERVER.

for example

if($_SERVER['is_special']) {     echo "Yeah for us!"; } else {     echo "No you fool!"; } 

I realize I ask a lot of questions that the answer is no so feel free to say so.

Try the SetEnv directive:

SetEnv is_special foobar
