What is the Internet proxy server
The Internet proxy server is the server that sits between the client application and a real server. The server Internet proxy has the function of intercepting all requests to the real server and see if the request can be fulfilled by him. If this is not possible, then it is passed the request to the server.
If used in an organization on the Internet proxy server, as well as the role it plays in all situations, also have function to ensure control and security. The Internet proxy server is connected to a gateway server. This serves to separate the corporate network from other networks. The Internet proxy server is also associated with a firewall that is used to protect the corporate network from any intrusion from outside.
The Internet proxy server receives requests for web pages or any other Internet services to the user. Then if the filtering requirements are passed proxy server controls Internet its cache for other pages downloaded (this assuming that the Internet proxy server is a cache server as well.) If the web pages required are declared by the Internet proxy server are returned to the user. In this case it is not necessary for the Internet proxy server that transmits the request. If the page does is in the cache, then the Internet proxy server must act as a client as well using its own IP address to request the website from other servers found on the Internet. When the desired page is returned, the Internet proxy server that informs the initial request and then sent to the user.
In user's eyes, the Internet proxy server seems to be invisible. This is due to the request and the response is so fast that the user has 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 role.
There are two main reasons why Internet proxy servers are used. One of them is to improve the performance and second to filter the requests. The Internet proxy server can improve performance for users because the Internet proxy server actually saves all requests that the user has done, so Internet operations much faster. The second reason why servers Internet proxy is used to filter applications. This could be seen in schools or workplaces where employees are not allowed to visit certain websites. This is easily done by configuring the Internet proxy server is used.
