Browsing is a two-sided process. On the initial stage of the connection the IP address is being determined . Then, to receive any information from a web-server in the Internet your browser sends a request for a page. This request contains some important details related to the privacy of the user, e.g. operating system, browser name and version, referrer page, user's preferred language. These details can compromise your privacy when surfing.
Referrer page is the page you visited last before going to any other page. For example, if you were at your home page, and then moved to this page, then your home page is the referrer. By this refferer web site owner can define from what site you have got on his site and to define what pages you have been seen on his site.
User's language means your operating system language settings and/or your browser language settings. This detail can point to your nationality, for example, giving a hint to the country you reside.
The IP address - it is the most important detail, which can lead to your ISP and then to you personally. For example, by IP address is possible to define your country. (a small sample of what a web site owner can find out about you)
All these details - language settings, referrer page - can be controlled by the user. IP address is the most critical detail since an Internet user cannot control it.
To control IP address you can use two methods - Proxy Servers or Anonymizer.
Method #1: use Proxy Servers
When you use Proxy Servers web pages are retrieved by the proxy server rather than by the person actually browsing the Web (you). But there are several important distinctions: proxy servers don't help with cookies, hostile applets or code. In most of the cases they do just one thing: they conceal your real geograhic location.

Not all proxy servers are truly anonymous. Some of them let the system administrator of the site that you visit via a proxy server find out the IP address from which the proxy server is accessed, i.e. your real IP address. You can perform an anonymity check test: http://www.all-nettools.com/toolbox
Method #2: Anonymizers
One can surf anonymously with the help of a nice services called the anonymizers. The anonymizers does the job for you, securing you from many potential dangers. You can choose between pay or free service, but free service implies certain limitations such as 30 seconds delay before pages are loaded, and only HTTP (pay service allows FTP and HTTPS). corenets made a real revolution in the industry.
