I am having problem with $_SERVER['HTTP_REFERER'] i put this in my PHP coding however it is giving me the error in IE6.0 however in Firefox it is working perfectly. I see with print_r($_SERVER) in FF it is showing HTTP_REFERER in the array however is NOT showing in the IE6.0.

It seems that it is browser specific. Is there any alternative to $_SERVER['HTTP_REFERER'] which works in All the browsers or in anyway i can make $_SERVER['HTTP_REFERER'] work in all the browsers.

Thanks !!
