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