A tutorial about proxies


Proxies are caches that relay data. When you configure your web browser to use a proxy, it never connects to the URL. Instead it always connects to the proxy server, and asks it to get the URL for you. It works similarly with other type of services such as IRC, ICQ etc. There'll won't be direct connection between you and the server, so your real IP address won't be revealed to the server. When you view a website on the server, the server won't see your IP. Some of web proxies do not support forwarding of the cookies whose support is required by some of the websites (for ex. Hotmail).
Here are some anonymous proxies that you can use to surf anonymously (notice that some of these may be a payed service):
Aixs -
Rewebber -
Anonymizer -
The Cloak -
Clearly Drunk-
You'll highly probably find many websites that provide the lists of unauthorized proxies and re mailers . Such lists are being compiled usually with the help of port scanners or exploit scanners, scanning for computers with win gate or other proxies' backdoors. Using these proxies is illegal, and is being considered as unauthorized access of computer. If you get such list to your hands, check if the info is legal or compiled by script kiddie, and act accordingly.
If you anyhow decide not to use proxy, at least do not forget to remove your personal information from your browser. After you remove details like your name and e-mail address from your browser, the only info a Web site can sniff out is your ISP's address and geographical location. Also Java and JavaScript applets can take control of your browser unexpectedly, and if you are surfing to unknown and potentially dangerous places you should be aware of that. There are exploitable browser bugs (mainly Internet explorer ones) reported ever week.
