HTTP Referrer NULL   

When a pop-up is fired and closed . the pop-up  refreshes the mother window. 
but returns the HTTP_REFERRER as null


my logic is to redirect  the page  to home page if HTTP_REFERRER is null

now when client clicks  on browser refresh button its being redirected to 
home page

any logic for this
