Understanding Functions and Types of Proxy

This time I will discuss Understanding Functions and Types of Proxy" 
For the moment is a lot of vpn application that can open a site that is blocked by a country using Proxy Tunnel, but not all proxy servers that can do that.

their own proxy server is a computer that can act as more computers to request the content 
from internet sites.

Proxy itself consists of:

Transparent Proxy (Transparent Proxy)

°  Proxy transparent proxy is one type that should not be used. Because of this type is a proxy entirely made no secret of its IP address, so that the user's IP address will be visible to the public in cyberspace. Even the use of a transparent proxy is also touted to make the user's IP address is blocked (banned) permanently and this also makes the user can not access certain websites

Anonymous Proxy (Anonymous Proxy)

° Proxy anonymous is a kind of proxy that does not make its original IP address is detected, but can be seen only IP address that is not suspicious pseudonyms in cyberspace. As for when users access the Internet, the IP address is mandatory items that must exist in order that users can connect to the internet. Without the IP address it is impossible for the user the possibility to connect to the internet

High Anonymity Proxy

° Proxy this one does not define itself as a proxy server, so it does not provide an IP address. And when a user accesses a site, then the user's IP address will not be readable by the respective sites and the Internet, but it reads as a client.Indirectly this means that high anonymity proxies very secretive about its IP address

distorting Proxy

° Distorting proxy function is similar to an anonymous proxy, which are equally not make the original IP address of its looks. But the difference lies in the anonymous proxy-if genuine change its IP address into the IP address of the proxy server, then this is precisely capable of distorting proxy manipulate the user's original IP address. While the original IP itself can only be seen in the HTTP HEADER

Reverse Proxy

° Reverse proxies are basically used to provide a path to many user requests from the Internet through a firewall that is isolated or through private networks. As for its own function, reverse proxy is used to prevent users from connecting to the internet with access that is not monitored

Functions of Proxy:

÷ Sharing connection

° Proxy acts as a  gate  that constitutes the border between the local network with the external network. Gateway apply also as a point at which some connections and network connections are also connected. Therefore, the connection from the network to the Internet will use a connection that is owned by  the gateway together (  sharing a connection

÷ Filtering

° The proxy can be enabled to work with firewalls that filter that can be used for the outside network. This filtering function can also be done to deny access to specific web sites and at certain times too

÷ Caching

° A proxy server has a storage object object that has been retrieved from servers on the Internet. With this command it will be stored cache objects are various demands /  requests from users that was obtained from iternet
