HTTP_REFERER

[Anon]

Hi,

does $HTTP_REFERER only work, if you are redirected from a page within the same domain?

An example:
http://domain1.com/test.php has a link to http://domain1.com/result.php

In result.php $HTTP_REFERER has the value: "http://domain1.com/test.php" - work fine!!!

Exampel 2:
http://domain1.com/test.php has a link to http://domain2.com/result2.php

In result2.php $HTTP_REFERER has the value: "" - ??? Why?

I use Win2K, Apache 1.3.19, IE 5.5 and PHP 4.x.

Sincerely,
Kenneth

Kenneth,

$HTTP_REFERER is set by your browser, and is optional. If your browser supports sending this HTTP header, then it the only instance it should not send one is if the request is sent from a source that does not have its own URI.

If this code is essential, you should pass it as an argument to prevent possible mistakes.

Can you post the code here?

Regards,

David Grant
