What tracking tool beside IP checking & cookie reading are there?
I thought that IP checking and cookie writing and then reading were the only 2 ways
for a server to keep track of a user, but apparently there is another way.
What is that?
For example, this site is able to know who I am, even though I have cleared my
Cookies and use a different IP than the original IP I used to visit it 1st.
How is that possible?
How can a site keep track of you beside IP tracking and Cookie writhing / reading?
This issue/question has really been baffling me.

There are also the loosely termed 'supercookies' which is a technique based on multiple local data storage e.g html5 dom storage, flash local shared object, java and silverlight data caches, and also browser/OS/IP metric fingerprinting, which they use to store, retrieve and regenerate data associated with a user.
