Identification by web site

[Rosh]

Hi all,

I'm trying to understand how asite can know that I open in it 2 acounts when I connect to the internet with 2 differents IP address, but using the same computer.
Are computers identified by web apps and web sites.
I'm talking about identifiers other then cookies, as these can be easily deleted.
Where would I be able to find some more info about computer identification on the internet?

Rosh :rolleyes:
