dial-up access is a cheap and practical way to access the Internet for small groups of users or home users. On the LAN, through Proxy Server software can solve the problem of multi-user sharing access to the Internet, the proxy server is essentially a bridge between the user community and the Internet, in order to achieve its network users access to the Internet.

Static agent needs to be written before the proxy class, which caused a lot of duplication of code, so we through dynamic agents in the runtime dynamic generation of business class
Are you unable to access more exciting websites because of the limitations of the network segment? Are you unable to log on to the QQ server because of port restrictions? At this point, if a person with you said "to use proxy server", you are confused what is the proxy server? In fact, the proxy server is not as mysterious as you think. Let me take you today. A w

Note that the commonly used proxy server for browsing Web pages is typically a dedicated HTTP proxy, which is different from socks. Therefore, you can browse the Web page does not mean that you must be able to access the Internet through socks. A common firewa

3, improve access speed: Typically, the proxy server sets a large hard disk buffer (possibly up to several GB or greater), when the outside information is passed, it is also saved to the buffer, when other users access the same information, then directly from the buffer out of the information to the user, to improve access speed.

First, the server commonly used ports
Each host (hosts) on the Internet has a unique address (IP), but the same host may provide more than one service, such as the FTP service, the WWW service, and so on, so that each service occupies one port of that host.
The common ports used by proxy servers are:
HTTP Proxy: 80/8080/3128/8081/9080
Socks Agent: 1080
FTP Agent: 21
Telnet Agent: 23

When it comes to proxy servers, the first thing we can think of is a dedicated Proxy server Web site that, in some cases, speeds up access to the Internet. In fact, in the need to access the external LAN, we can set up the agent, the number of visits to save the page in the cache, thereby "improve" the network speed. More importantly, we can use the proxy server
