The driving force behind this trip is my curiosity about this western area, its people, culture, landscape.
A friend of mine ask me if a server can know where we come from before we go to that server (referal link). YES. This information is the field "HTTP_REFERRER" in $_SERVER of the coming request. Here is an example: http://113.161.96.198/referal/ For the reason of SEO, some guys do not want any server know about this referal link that points to their own server. Here are some solutions: HTML5: Add norefer attribute No REFERRER PHP redirect: <?php header( 'Location: http://113.161.96.198/referal/ ' ) ; ?> .... lot of solutions lol
