No I’m not talking about some on line game of football, but the real type of headers that get sent around the Internet everyday. To be more specific I’m talking about HTTP headers, which are sent with every little web request you send from your computer. They contain a wealth of information about your online presence.
On their own, it doesn’t sound much but when you combine all the information sent in an average web connection between you and a website it actually builds up quite a picture of your and your computer. Typically they will contain IP address, host names (of your computer and servers), Operating systems and browser versions.
In fact the exact same information that a decent hacker would require to start breaking into your computer. If you are concerned about security and the thought of anonymous secure surfing appeals, then you should stop your HTTP header leaking information about you online. There are many security applications that can do this usually by allowing you to surf behind a secure proxy server of some kind.
