Please be aware that the use of proxy servers
without the express permission from the
owner of the proxy server may be illegal in
some states and/or countries. Use at your
own risk.Use your favorite search engine
and search for 'proxy server list'. You'll find
many sites with lists of proxy servers, their
IP address, the port they listen on, and
usually what country they are in. Write down
a few of them.

5. Proxy TypesProxy Types

6. Transparent ProxyTransparent Proxy
This type of proxy server identifies itself as a
proxy server and also makes the original IP
address available through the http headers.
These are generally used for their ability to
cache websites and do not effectively
provide any anonymity to those who use
them. However, the use of a transparent
proxy will get you around simple IP bans.
They are transparent in the terms that your
IP address is exposed, not transparent in
the terms that you do not know that you are
using it

7. Anonymous ProxyAnonymous Proxy
This type of proxy server indentifies itself as a
proxy server, but does not make the original
IP address available. This type of proxy
server is detectable, but provides
reasonable anonymity for most users.

8. Distorting ProxyDistorting Proxy
This type of proxy server identifies itself as a
proxy server, but make an incorrect original
IP address available through the http
headers.

9. High Anonymity ProxyHigh Anonymity Proxy
This type of proxy server does not identify
itself as a proxy server and does not make
available the original IP address.

11. Web proxiesWeb proxies
A common proxy application is a caching Web
proxy. This provides a nearby cache of Web
pages and files available on remote Web
servers, allowing local network clients to
access them more quickly or reliably.

12. When it receives a request for a Web
resource (specified by a URL), a caching
proxy looks for the resulting URL in its local
cache. If found, it returns the document
immediately. Otherwise it fetches it from the
remote server, returns it to the requester
and saves a copy in the cache. The cache
usually uses an expiry algorithm to remove
documents from the cache, according to
their age, size, and access history. Two
simple cache algorithms are Least Recently
Used (LRU) and Least Frequently Used

13. Web proxies can also filter the content of Web
pages served. Some censorware
applications - which attempt to block
offensive Web content - are implemented as
Web proxies. Other web proxies reformat
web pages for a specific purpose or
audience; for example, Skweezer reformats
web pages for cell phones and PDAs.
Network operators can also deploy proxies
to intercept computer viruses and other
hostile content served from remote Web
pages.
