Proxy Sites 101 – General Information on Proxy Servers
March 8th, 2009. Published under Technology. No Comments.
A proxy, also known as a “proxy server” or “application level gateway”, is an intermediary application or a system in the computer networks that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the Internet. Proxy sites are often where you can locate these proxy servers
A proxy server usually performs multiple roles: it always acts as a security and privacy mechanism, and its other functions are as a network management or a performance enhancement tool. If one or more Internet sites are frequently requested, these are likely to be in the proxy’s cache, which will improve user response time. Proxies are also used as a sort of firewall, because it isolates you from connecting to the Internet. You can also obtain access to blocked websites and bypass work, school, college or company internet filters with the help of a proxy.
Another use for a proxy server is to implement anonymous Web surfing. Using an anonymous web surfing proxy is recommended because surfing the web can be risky and your IP address could expose some of your personal data to the rest of the world when you’re surfing the net. When you visit this web page from a free web-based proxy you can have a completely different IP address. For example, you are currently browsing this web site using the IP address 121.96.233.170. As far as the Internet is concerned, the only IP address on the remote server(s) is the proxy’s IP address. Only the proxy server knows the customer’s IP address.
Make sure, however, that you choose your proxy carefully as there are a lot of scam proxy sites breeding the internet that sell their users information to online felons.
