Proxy is a computer that acts as gateway between a local network (e.g., all the computers at one company or in one building) and a larger network such as the Internet. Proxy servers provide increased performance and security. Often, these monitor users access to the outside network.
A proxy server operates by being in between sender and receiver. . Acting as a buffer between internal and external networks, the internal network is saved from intruders.
Some proxy servers are a group of applications or servers that block common Internet services. A proxy server uses a network addressing scheme to present one organization-wide IP address to the Internet. The server funnels all user requests to the Internet and returns responses to the appropriate users. In addition to restricting access from outside, this mechanism can prevent inside users from reaching specific Internet resources (e.g., certain web sites).
Proxies may also cache web pages. As a user accesses a outside resource, a copy is stored locally. The next time a user accesses the same resource, the proxy serves the local copy, improving performance.
Some Other Uses of Proxy Servers:
The above was the usage of proxies in a local area network. Of course, people use proxy servers for other reasons as well. One example is to access region-restricted content. For example, someone from Asia trying to access Hulu will not be allowed to. But if they connect to a U.S. based proxy first, the restricted content can be viewed. Similarly persons living in the US want to access BBC's iPlayer to access their content. They would need to connect to a UK proxy .
Very common utilization of Proxy Servers is to bypass censorship at places where access to internet is blocked.
The use of proxies by criminals is also very common to hide their real location. They can even chain proxy servers together to increase the difficulty of being tracked. The usage of proxies is not limited to seeing region specific content and to hide criminal's location. Malware threats roaming the net in search of vulnerable systems, would find only the proxy which usually will be well prepared for threats. Use of proxies by security people is also very common. While trying to break into the criminal network, one would obviously not want to give his / her IP address to the criminals. Similarly, privacy conscious people use anonymous proxies to to prevent their information to leak out. Accessing internet without anonymous proxies exposes your IP address and other information which can be used to hack your computer, steal banking and credit card information, and even hijack your identity. This information may include credit card information, financial accounts information etc
Web Proxies to Bypass Internet Censors:
Web Proxy accepts target URLs using a text box on the main page of proxy site, processes the request, and displays the results in the user's browser. Consequently it is used to circumvent internet censors and retrieve the blocked websites to the blocked user.
Web proxies may or may not hide the user's IP address based on whether the proxy has been setup to perform this function or not. To be completely sure of your safety online, normally one may not rely on web proxies. Privacy conscious people use paid proxies or VPNs (Virtual Private Networks). VPNs charge quite nominally. I have been using to be anonymous and safe on virtual world is VPNAce. VPNAce offer no obligation trial to test run their services before committing. Click to check the best and reasonably priced VPN.
