6	* Say you have a rewrite rule that points to a PHP script and you would like to pass some information
7	* along to the PHP. Usually, you will just pass it in the query string. But this won't do if the information
8	* is sensitive. In that case, there are some tricks available. The trick being tested here sets tells the
9	* RewriteRule directive to set an environment variable which a RequestHeader directive picks up on and passes
10	* on to the script in a request header.
