Right, you're obviously not getting this, so let's take it step by step. (1) Your browser requests https://computing.eng.iastate.edu/mambo/index.php?option=content&task=view&i d=159&Itemid=162 (2) This fires the script /mambo/index.php on your server. (3) Script finds all conditions in the first if() are met, so tests $_SERVER['HTTPS']. (4) ... finding it is not set, it issues a Location: redirect to https://computing.eng.iastate.edu/mambo/index.php?option=content&task=view&i d=159&Itemid=162 (5) Browser sees the redirect, and issues a new request for https://computing.eng.iastate.edu/mambo/index.php?option=content&task=view&i d=159&Itemid=162; at this point, it also changes the URL displayed in its address bar. (6) This seems to be where you are confused -- WHICH PAGE DO YOU THINK THIS IS GOING TO LOAD? (6a) Server sees new request, this time via https, to exactly the same script as before, so fires the script /mambo/index.php again. (7) See (3). (8) This time it finds $_SERVER['HTTPS'] is set (or =='on', depending), and echos 'You are in HTTPS mode'. (9) QED Which step isn't what you were expecting? Cheers!
