What is proxy server?
A proxy server is a kind of buffer between your
computer and the Internet resources you are accessing (Web sites, FTP archives
and others.). The data you request come to the proxy first, and only then it transmits
the data to you.
Why I need to use proxy servers?
1. Transfer
speed improvement. If the file you requested was received before to your proxy
server, then proxy server will interrupt this file request and you will receive
the file directly from proxy. However need to know, you can got the "speed down"
effect. This effect appears when your proxy has long answer time because there
is slow connection between you and your proxy server.
2. Security and
privacy. Anonymous proxies destroys information about your computer in the
requests header. So you can safely surf the net and your information will never
be used by spammers and hackers .
3. Sometimes you encounter some problems
while accessing to web server (for example, web-chat). You have mistaken while
working with some data and / or the server administrator restricted access from
your IP. So you can use the anonymous proxy and try to access
again.
Types of proxy:
Transparent proxy: -iIs one of the methods to force users to use proxy
within local network. They use proxy without awareness, so they do not know even
that in fact they use proxy. Such proxy is not even configuring by users.
Anonymous proxy:- It is a proxy server which is free and open for
everybody on the Internet. There is quite a large number of public proxy servers
in many countries but most of them are not anonymous.
High anonymity (elite proxy): - High Anonymous (real anonymous!) proxy
servers don't transfer the information about the IP-address of the client, and
thus effectively hide the information about you and your surfing interests.
Besides that, some proxy servers can also hide the very fact that you are
surfing through a proxy server! Anonymous proxies can be used for all kinds of
Web-services, such as Web-Mail (MSN Hot Mail, Yahoo mail), web-chat rooms, FTP
archives, and others ...
