In the HTTP_REFERER refrence of Predifined Variables in the PHP manual, it warns that "not all browsers will set this".
I am working on some security setting on a project and started to use the HTTP_REFERER variable when I noticed this warning. Does anyone know what browsers do not send a HTTP_REFERER?
