Settings for Proxy Server

To set up a proxy server, you must first know the proxy server address and port number, and then fill in the appropriate address and port number in the agent server settings bar of IE or NC. Suppose we have a proxy server with the address Proxy.net.net, the port number is 3000, the configuration method in IE is to use the Internet option/connection/proxy Server to view the menu, and then to the check box in front of the Internet option through the proxy server. In the Address box to fill in the proxy server address, as in this case, assume that the proxy server address is proxy.net.net, and then fill in the Port box with the slogan 3000, click the bottom of the application button, and then click OK, set up. The next time you use IE, users will find that no matter what Web site you browse, ie always first connect with the proxy server. With the NC, set a little more complicated. Using the Preferences menu item under the Edit menu, and then selecting proxies under Advanced, select the second item manral proxy configuration in the right proxies option. and point to the view on the right ... button, you will be the Proxy server configuration interface, in the proxy server address and Port number column fill in the corresponding content, click OK, back to the Parameter Settings window, and then click OK, Proxy Server setup work completed. When the customer browses the webpage again, will automatically send the request to the proxy server which you set up, and obtains the data, when browsing the website, either the IE or the NC can clearly see in the browser status bar the first to connect the proxy server, then even the target website process.

However, do not confuse Proxy server and router, Proxy server is built on the application layer of the service software, and router is a network device or a computer, it is working in the IP layer, The data is forwarded after it reaches the IP layer. Generally a proxy server work on a computer that has both a modem and a network card. Different proxy server software provides different services, generally provide www,ftp and other commonly used services. Each passenger plane in the intranet must have a separate IP address and be configured to use Proxy server in "connection" in the aircraft's "Control Panel-internet " and point to proxy server  The port number of the IP address and service. When the Proxy server is started, it will use Winsock.dll to open up a designated service port, waiting for the passenger plane's request. When the Proxy server modem dials the Internet, your proxy server can work. When you send a connection request to your IE, your airliner will send the packet to Proxy server, when the server captures the IP packet, first analyze what it is request, if it is HTTP request,proxy  The server sends an HTTP request to your ISP, and when the Proxy server receives a response, it forwards the IP packet to the internal network, and your passenger plane gets the IP packet. In addition, your proxy server can also be a good firewall. For specific operations, please refer to your proxy server Readme file.

When you visit a Web server on the Internet, do you know how much personal information will be leaked to others? In the process of accessing the Internet, the Web browser will at least more than 20 items about your personal information to the Web server silently without your awareness. This personal information is not a big problem if it is delivered to a reputable web site or a Web server for a large enterprise. It would be deeply disturbing to be sent to a Web server whose Web site is not known to all. The information that a Web browser sends to a Web server is, in the jargon, "environment variables." The main contents are: (1) The IP address (remote_a DDR) and host name (Remote_host) assigned to the computer, (2) the port serial number (Remote_port) used by the Web browser (3) The product name (http_user_agent) of the Web browser and (4) The latest page address (http_referer) of the Web site visited.

Although the above items do not contain personal information such as e-mail addresses and names, the IP address and hostname in (1) are really difficult to be assured in terms of security, but what methods can you use to obscure your IP address?

To solve this problem is very simple indeed. Simply access the Web server through a proxy server. The role of a proxy server is that it can withstand access requests from various terminals for the Web server. In the enterprise network, the proxy server is set on the part of the company's intranet that is linked to the Internet. When dialing on the Internet, you can use the proxy server provided by the Internet connection provider.
