Having empty session variable osCsid

[rupak_karmadhar]

Hi,

I am having a problem with my site www.phonempire.com. I am not getting the session variable osCsid globaly. I have checked that the session id is generating. If you see my site, click on a product image and go the product info page. There you will see four buttons. Click on any one of them, the page will go to the index.php. If you see the url when you keep the mouse over a link you will find that osCsid is absent.

 

Please any one help me. How can I get this session variable? I am in a greate trouble.
