jQuery ajax referer url

Question

How can I get the url of the referer in an ajax request?

A file named main.php has jQuery that sends an ajax call to a file named request.php.

Is it possible to somehow figure out the referer when I'm on request.php? To be precise, I want to print the string "main.php" (dynamically) while running request.php.

Normally the the browser will send the referer page using the header Referer as part of the ajax request so you can read it

So you could do something like

$_SERVER['HTTP_REFERER']

How do you get the 'referer' header in PHP?

If you don't want to depend on the default Referer header, pass a custom header of your own

$(document).ajaxSend(function (event, jqXHR) {
    jqXHR.setRequestHeader('my-referer', 'some-value');
});

Can I be sure that the HTTP_REFERER always exists? Or is it safer for me to add the current page to the ajax request itself? – sleepless_in_seattle Nov 05 '14 at 10:12
If you have control over ajax request... you can always set a custom request header – Arun P Johny Nov 05 '14 at 10:14
