What Is The Internet Proxy Server

What Is The Internet Proxy Server
By Stefan Jechel

The Internet proxy server is the server that is situated between the client application and an actual server. The Internet proxy server has the role of intercepting every request to the actual server and see if the request can be fulfilled by it. If that is not possible, then it must forward the request to the other server.

If used in an enterprise the Internet proxy server besides the role that it plays in all situations, also have the role of ensuring control and security. This Internet proxy server is linked to a gateway server. This has the role of separating the network of the enterprise from other networks. The Internet proxy server is also associated with a firewall server that is used to protect the network of the enterprise from any intrusions from the outside.

The Internet proxy server receives requests from web pages or any other Internet services from the user. Then if the filtering requirements are passed, the Internet proxy server checks its cache for other downloaded pages( this assuming that the Internet proxy server is a cache server as well ). If the web pages that are required are then found by the Internet proxy server, they are returned to the user. In this case there is no need for the Internet proxy server to forward the request. In case the page can not be found in the cache, then the Internet proxy server must act as a client as thus use its own IP address to request the web page from other servers that are found on the Internet. When the required page is then returned, the Internet proxy server reports it to the initial request and then it is forwarded to the user.

In the users eye, the Internet proxy server seems to be invisible. This is because the request and the response are so quick that the user is under the impression that they are made directly with the Internet server that was addressed. However, this is not the case and the Internet proxy server actually plays a very important part.

There are two main reasons why Internet proxy servers are used. One is to improve the performance and the second to filter the requests. The Internet proxy server can improve the performance for users, because the Internet proxy server actually saves all the requests that the user has made, thus making Internet operations a lot faster. The second reason why Internet proxy servers are used is to filter requests. This operation might be seen in schools or workplaces, where the employees are not allowed to visit certain web sites. This can be very easily done by configuring the Internet proxy server that is used.

Questions and Answers About Proxy Server
By John Hu

What is a proxy server

A Proxy (proxy server) is a server that acts as mediator between the client (the computer of a user) and server (the computer on the other ends of network connection on which the information requested by the user appears for example web server site.) When clients request data from an Internet resource, traffic goes from your web browser/application first through the proxy before it reaches the requested sources and back through the proxy. Then the proxy will transmit the data (information) to you.

Why I need to use a proxy server

1. Transfer speed improvement. If the file you requested was received before to your proxy server, then proxy server will interrupt this file request and you will receive the file directly from proxy. However need to know, you can got the "speed down" effect. This effect appears when your proxy has long answer time because there is slow connection between you and your proxy server.

2. Security and privacy. Anonymous proxies destroys information about your computer in the requests header. So you can safely surf the net and your information will never be used by hackers and spammers.

3. Sometimes you encounter some problems while accessing to web server (for example, web-chat). You have mistaken while working with some data and / or the server administrator restricted access from your IP. So you can use the anonymous proxy and try to access again.

How can I get fresh proxy server information?

Every proxy server is inclusive of an IP address and a proxy port that is listed next to the address. You can search "free proxy list" on google to get newest proxy servers. Here is a daily updated proxy list I recommend: http://www.aplusproxy.com/proxylist/index.php

Proxy Sites - What Are They

Proxy Sites - What Are They
By [http://ezinearticles.com/?expert=Karl_Amerson]Karl Amerson

Have you heard the words proxy server or proxy site? If you have, but you do not know what it means you will want to read on. I confess to being a little ignorant in the world of online websites and proxy sites. You see I may be handy at finding things, but that doesn’t mean I understand how it all works. So first of all to understand what a proxy site is you need to know what they are.

A proxy site or server allows you to surf the Internet with a buffer. In other words the proxy server will hide your IP address while providing you with information. Often a proxy server will help you download pages quicker or files with more speed. This is helpful if you like to download music, movies, or other files to your computer and want to remain safe.

Proxy sites are often where you can locate these proxy servers. If you are interested in finding a proxy site you just need to search for them with a search engine. Google or even Yahoo! can point you towards proxy sites. The proxy sites allow you to find a proxy server that will help you remain anonymous online while you are downloading your files.

The benefit of course is the faster speed you can get your downloads. When you spend hours online finding music to download to your phone or MP3 player you want to know that your files are being downloaded as fast as possible. Other reasons or benefits for using proxy sites is the hidden IP address. You can search online while making it difficult for hackers to infiltrate you computer with viruses or other damaging things. Proxy sites have been created to protect you and make downloads move at a better pace. You probably didn’t even know you where using a proxy site when you downloaded music and it gives you two or three places to download from.

Proxy Websites

I wanted to take a break form doing reviews and things like that today, this will be a semi informational post regarding proxies. I'm sure many of you have heard to word used, and maybe and came across a website of two that is a proxy. Well what exactly is a proxy?

There are two different types of proxy. One involves editing something on your local machine. The other is just visiting the proxy website and putting in the address you wish to visit.

A proxy is a way for you to not only get privacy, it also is a way to view websites that are blocked on your network. Such as your school, work place, or even the library. When you use a proxy, or proxy website all of the information is transferred through that proxy instead of your local machine. This means not only a whole new level of privacy for you, but this also means any pesky limitations on your computer or network do not apply.

If you are interested in a web proxy one I like to use is Advected.com. It's fast, free, and it also has small shortcuts to very common websites that are blocked by most network administrators. If you are interested running a proxy on your local machine you can check out Proxy4free.com. If you are unsure oh how to set the proxy on your computer read around their site, there are a few guides that you can use. But I always found it way more simple to use a web based proxy such as Advected.com [http://clrly.com/]Clrly Technology Blog
