Question

For example,
I have an ajax request from the page http://www.abc.com/xyz/1 to the function controlling ajax.

Is there any way except sending it through the parameters so that I could know that in the function I can fetch http://www.abc.com/xyz/1 and realise that the ajax request came from here?

Answer 1

If the server wants to know from which page, or the server’s location, then you can use this in the end, if PHP:

die($_SERVER["HTTP_HOST"] . $_SERVER["HTTP_REFERER"]);
