i have used ip address to find the unique details about the request but it fails in some condition as ip is same for many user when they access my site eventhough they are requesting from different machine . i used "HTTP_X_FORWARDED_FOR" , "REMOTE_ADDR" everything but still it tells same ip address . how to find unique details about the machine which is requesting .

well if you want to uniquely identify a request or user, IP is not always safe option as people in enterprises use internet from behind the proxy, in that case you will always get the same IP for all the requests from different users.

The safest way that i would use it to save cookies in user's browser, this is the way google and other big names do to ensure that they know the request is coming from same browser again.

here is a sample:-
