Large numbers of people who use computers are generally not familiar with a proxy server and how well it works while they are browsing data. Basically whenever a Pc is connected with internet suddenly the internet protocol address of that particular Pc is transferred to the server. It is important to know the location of the web request. Every Pc is assigned a special internet protocol address which acts and an Identity proof; it includes all the details of computer of the user. Such information is visible to others and also can be logged for the purpose of monitoring and upgrading. The administrator of network can also see all that information for all the users. So the question arises in the mind is what exactly is a proxy server? Basically it acts as a medium among the personal computer and host computer that the user is going to use. Any kind of information exchange among user and the hosting computer is controlled by a server. For this, a request is to be sent to server specially, and its output is provided to proxy server which is then transferred to the user. No direct exchange of information is actually there. That is why it may appear as if the information is received through server.

The one and the only alternative to know that the data that is transferred by the user to go the way of large files kept, by this method the proxy server is able to hide the individual from remote server. There are several functions of the proxy server and they are.

Proxy servers can simply raise the velocity of the all accessed resources through servers. This is achieved by hiding responses for same request to all the users. This automatically helps in saving time.

This is one of the most important functions of a proxy server. It maintains data regarding request as well as response in a specific file. This file is possible to use for several book keeping tasks.

Several network administrators commonly need an ethical need to ban some sites that they do not want or sites that are illegal. At this stage a proxy server helps them to block such sites.

To use sites are banned over a particular network, the proxy servers are preferred to gain instant access to such sites. The network just notes the internet protocol address of these proxy sites so allows it. This is best for such web pages that are commonly banned in a school or firm websites.

Use of regionally banned resources is allowed in case servers are adopted. For instance, the elimination of such information is possible which is abused or miss lead any one.

In order to make sensitive contents fully secured from being hacked, few firms prefer them as a gateway to control data traffic.

For security reasons, users have the option to hide their identity from a proxy server. Many do not want to show their identity while on internet. So for them it is beneficial. They do not allow your identify to be cached by anyone and hence keep you anonymous. They have two sub categories - elite as well as disguised. Elite under any circumstances not permit itself as a proxy server to the other end. However a disguised will provide enough proof to be realized by the end machine that surely it is a proxy server.

Several unwanted programs are there that host computers transfer along with requested information that may be dangerous to the server at another end, so proxy servers contain a filter that scan data before delivering it on other end.

There are many kinds of proxies but the commonly used are HTTP, filtering as well as socks. The HTTP is used similar traffic and filtering proxies are usually located at work and are preferred for banning some websites. In addition to this it can also be used to avoid wastage of bandwidth. Socks proxies are highly referred for providing path to other traffic.

Rather than this there is an intercepting proxy which is a kind of proxy which intercepts basic information exchange, without users requiring any unique configuration in order to use proxy.

It is necessary that you must get proxy servers from a best firm and also ensure that in their regulations they mention that they will not going to store log files. It is recommended to go online if you are looking for more information on proxy servers.
