Is there any way to distinguish users behind NAT without cookies?


Is there any way to distinguish users behind a NAT firewall without cookies? I would like to know because sometimes multiple people behind one IP is using my website, and I can't distinguish them.

Yes and no: depends on the NAT behaviour.
Try reading the HTTP_X_FORWARDED_FOR in HTTP request (how depends on the language you are using)
