A server that sits between a client application as a Web browser and a real server. It intercepts all requests to the real server to see if it can meet the same application. If not, send the request to the real server.
Proxy servers have two main purposes:
Improving Performance: Proxy servers can improve performance for groups of users. This is because it saves the results of all requests for a certain amount of time. Consider the case where both user X and user Y access the World Wide Web through a proxy server. First user X requests a particular Web page, we’ll call Page 1. Sometime later, user Y requests the same page. Instead of transmitting the request to the Web server resides on a page, which can be a long operation, the proxy server simply returns the Page 1 that it was brought to the user X. Since the proxy server is often on the same network as the user, this is a much faster operation. Real proxy servers support hundreds or thousands of users. The major online services like America Online, MSN and Yahoo, for example, employ a variety of proxy servers.
Filter applications: Proxy servers can also be used to filter applications. For example, a company might use a proxy server to prevent its employees have access to a specific set of websites.
The proxy server is responsible for conducting the activities carried out between the Internet and web browser applications that need to be implemented by clients. This server can sometimes restrict users to search for information about particular things. Mainly the server is responsible to see if all the request that had been generated can be easily obtained and accepted or not. For this person had to connect to the Internet in order to see the exact timing of the server is running.
Different types exist and each proxy server proxy server is responsible for performing various functions. The proxy server can be public, where the public can easily connect to the Internet and had been classified as private, then the proxy server allows certain persons to enter. The proxy server is responsible to improve and enhance server performance. The server performance has been improved so that the proxy allows the group of people interacting with each other. The server not only enhances performance but also the application that had been generated on its own or is not used then they can be easily filtered.
Applications can be filtered so that certain restrictions had been imposed on different websites that makes it difficult for people to enter the site and therefore will not be able to open that site and see what data it is contained. Server performance is increased so that each time you send the application to use, all information had been sent are saved and still holds the record is also for everyone and everything had been done before.
Kinds Of Proxy Websites:
Following are the four different types of proxy servers:
This type of proxy server identifies itself as a proxy server and makes the original IP address available through the http headers. These are generally used for its ability to cache web sites and do not effectively provide any anonymity to those who use them. However, using a transparent proxy will move simple IP ban. They are transparent in the terms that your IP address is exposed, not transparent in the terms you do not know they are using (the system is not specifically configured for use.)
This type of proxy server identifies itself as a proxy server, but it has the original IP address available. This type of proxy server is detected, but provides reasonable anonymity for most users.
This type of proxy server identifies itself as a proxy server, but make an incorrect original IP address available through the http headers.
High Anonymity Proxy
This type of proxy server identifies itself as a proxy server and not making available the original IP address.
Please be sure to read about the risks before using anonymous proxy server proxy.
