Returns true or false, indicating whether the connection is secure
(https). Note that the URI scheme (eg., http vs. https) must be determined
-through heuristics, and therefore the reliablity of $req->secure will depend
+through heuristics, and therefore the reliability of $req->secure will depend
on your server configuration. If you are serving secure pages on the standard
SSL port (443) and/or setting the HTTPS environment variable, $req->secure
should be valid.
