Types of Proxies
Transparent proxies
Transparent proxies are standard proxy servers that do not alter user information and leave it in its original format. So, they reveal IP addresses.
Transparent proxies handle all HTTP traffic, and a user need not adjust any personal settings.
These proxies enable a user to accelerate access to websites defined by him - mostly, to frequently visited locations. Performance is increased by caching content. Transparent proxies commonly operate faster than elite and anonymous proxy servers as they reduce upstream bandwidth usage.
Employers apply this kind of proxies for restricting access to specific resources (social networks, etc.).
Its key drawback is a low level of anonymity. Transparent proxies are mainly used for driving up counters values, downloading files from file hosting services, and for blocking local firewalls.
Transparent proxies pass HTTP-headers in about the following way:
REMOTE_ADDR shows up proxys IP
HTTP_VIA shows a proxy software being used
HTTP_X_FORWARDER_FOR gives your IP address to a proxy.
Variable X in the line means its usage is not obligatory. Though Squid and other prominent proxy servers widely use this variable.
Anonymous proxies
As for caching, anonymous proxies have the same strengths as transparent servers. Besides, they offer another undeniable advantage represented in their name, that is, anonymity. The number of anonymity proxy users is heavily increasing, since confidentiality on the Internet means that your computer is secured from häçking, data loss/corruption and other malicious actions.
Anonymous proxies hide user info during web surfing, and randomly modify an IP-address. The resulting IP-address is not registered anywhere due to a simple fact: the value of HTTP_X_FORWARDER_FOR is not forwarded to the end-website. Impressive, isn't it?
Anonymous proxies forward these data packets:
REMOTE_ADDR shows up proxys IP
HTTP_VIA shows a proxy software being used
HTTP_X_FORWARDER_FOR gives your IP address to a proxy.
However, all header lines are filled in just to check the box and include no true information. And this just fits the bill for many users!
Elite proxies
Using an elite proxy is the most advanced degree of security as it provides the best protection and privacy on the Internet.
Elite proxies are your ideal disguise. This means that you leave no traces of using a proxy server. Your IP address will be fully hidden. The HTTP_X_FORWARDED_FOR, HTTP_PROXY_CONNECTION and HTTP_VIA headers are not forwarded at all. A host is not communicated either an IP address or a usage of the proxy. In this regard, elite proxies excel other proxy servers.
Elite proxies have a shortcoming: The REMOTE_ADDR header saves a proxy's IP-address. So, when forwarding packets of cøøkíés stored from your surfing without an elite proxy, websites will not identify you. Want to avoid this? Clean cache and cøøkíés in advance.
