traditional HTTP request might consists of the following:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:
1.8.1.4) Gecko/20070515 Firefox/2.0.0.4
But I want to know: what kind of envirnoment variable is only browser
know? (which mean server don't know, i.e. those data is not passing
thru using HTTP)
e.g.
screen width, screen height are example
i want more and perfer some specific one, which I can used to identify
a client behind the same IP
those data of coz should be get via javascript
