Proxy Server: What are they and what are they good?

I am writing this for those of you who have never heard of proxy servers. A proxy is a server, the server acts as an intermediary between a client (you) and others. As you probably know all websites and web-hosted services provided computers called servers. If you have a site or service hosted on a (local) or external (Internet, WWW) internal network, the terminal or a computer (client) communicate with the server directly (> Computer), the requested resource (website, media hosting service.)

As mentioned above, a proxy server acts as an intermediary between the user and the server host. Instead of direct communication with the server end, communication is your first pass through another computer. The proxy server communicates with the host server in your place, receives the requested information and passes it back to you. This is equivalent to ask to talk to a frienda third party for you.

But why do this? Proxies tend to have a bad reputation because they often used to circumvent content filtering mask, firewall, or illegal or offensive material. To be honest, I would venture that this is probably quite correct. But the proxy, like many other technologies were originally developed and are still used for a variety of "noble" intentions. Proxies are often mask the identity of computers on the internal network from prying eyes on the usedInternet (security) to accelerate and network resources using the web cache, such as content filtering for inbound and outbound traffic for viruses or potential losses of scanning - in short, the proxy server network components essential.

It showed an explosion of proxy servers in recent years. Why? People are increasingly demanding and deal with them, for one, by content filters at work or school. content filters are often implemented in work and schoolEnvironments in an attempt to staff and students access to "objectionable" material or the time and resources for using "non-productive" activities to keep you chat with friends on Facebook, watch videos or play stupid. It 's easy to understand why implement these filters. For the same reason, these filters are often poorly managed or being too strict and no exceptions to block some useful (sometimes necessary) resources.

Another reason to use proxy for anonymity.E 'effort to communicate via multiple proxy on a form for your computer's IP (Internet Protocol Address - a unique identifier that can be traced).

A quick Google search for the words "proxy list" or "proxy server" will take you to a variety of sites and lists of proxies to try.
