php HTTP_REFERER header, how to turn off or leave blank

Question

Hi
I'm using the following simple PHP proxy script but am getting a sporadic message at the destination site.

I'm thinking that perhaps it may have something to do with the HTTP_REFERER header, although I'm not explicitly defining it.

Can anyone tell me how to explicitly turn off or leave the HTTP_REFERER header blank?

Thanks in advance!

$url = $_GET['path'];
readfile($path);

Answer 1

I don't think the HTTP wrapper to readfile() sends any special headers, let alone REFERER.

What leads you to the conclusion that it does?
