There are many "clients" where the Location header don't work. Curl is a good example, you can determine to follow the Redirect or just skip it. curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false) Another example could be mobile phones, especially wml based, do not follow a redirection and you have to provide a "click here to redirect" link and relies on the user to follow the redirection. Do not trust that your client is always a browser. It could be anything that can open a connection and send a request. Also you can't know who is at the other side. The client can provide fake UA, IP, everything... or can't send anything but the need to make a valid request. -- Martin Scotta
