Alternative for $_SERVER['HTTP_REFERER'] PHP variable in MSIE

Question

Hi,

I have used $_SERVER['HTTP_REFERER'] variable in my application (used PHP). On Firefox above variables is wokring. But i observed that $_SERVER['HTTP_REFERER'] is not working on Microsoft Internet Explorer 8. I also got to know that HTTP_REFERER variable doesnt work on MSIE8 and MSIE7.

Please give me your suggestions, how to use $_SERVER['HTTP_REFERER'] variable to get rid on MSIE7/8 or is there any other alternative for $_SERVER['HTTP_REFERER'] variable

Thanks for your suggestion.
