In the day-to-day network, there are many uses, here we are familiar with some of the role of the summary and analysis, classification:
First, sharing network
The most common is to use a proxy server may be shared online, many people unconsciously in, for example, through sygate, wingate, isa, ccproxy, NT systems bring their own network sharing, and so on, can provide enterprise-class file ease Survival, reproduction and address filtering, and other services, to make full use of the limited export of local area network bandwidth to speed up the network within the user's access speed, can be solved only with a line of a IP, IP resources, with a lot of local area network for Internet access function, as well as A firewall, network and outside the quarantine network, and they provide a network to monitor and record the information transmission function to enhance the local area network security, and easy to manage users on the Internet.
Second, the visit to Deputy
Visit the Web site to speed up the pace in the emergence of network congestion or failure, through a proxy server website purpose of the visit. For example, A visit to site C, but A to C network problems can bypass the assumption that B is a proxy server, A through B, and then from B to C. You will recall that a few months ago, the network time is not normal, basic access to foreign sites can not, such as GOOGLE, YAHOO, and even the CCF are unable to visit, was very anxious. The results through a proxy server, can be found in the visit, good speed, in such circumstances, the proxy server will be able to play a big role. There is also a type of proxy server to back up a considerable number of cache files that if we visit by the current data in the proxy server's cache file can be read directly without having to re-connect to a remote Web server. In this way, to accelerate the pace of the visit.
Third, to prevent attacks
To hide their true address information, but also to hide their own IP, to prevent attacks by hackers. By analyzing the designated IP address, users can query to the current location. For example, we see that in a number of forums, the forum clearly marked the location of the current users to post, which is in accordance with the Forum members log on at the time of the IP address resolution. Weekdays, we have the most commonly used version of IP significantly QQ, "sending messages" window, you can view each other and resolve the IP location. When we use the proxy server corresponding agreement, will be able to reach their current location of the hidden purpose of the address.
Fourth, limit break
Proxy server can also break through the network restrictions. For example, Internet users on the LAN port, the purpose of the site, the agreement, games, instant messaging software, and other restrictions, can break through these constraints, I can see this message, how to break through local area network for Internet users will not repeat some of the restrictions. For example: GOOGLE We all like to use, in fact, to GOOGLE a function somewhat similar to the proxy server functionality, is a snapshot of the page, the site is frequent changes in address or Web site clearance, site of the server broke down, or has been updated But we still have to check before very useful information on the web page snapshot of the use Paishang, Google with its complex and fully automated search methods ruled out any man-made factors on the search results, to ensure that the page rank of an objective and fair , Google can easily, honest and objective to help you find valuable information online. GOOGLE has a massive database, if can not find server, Google's page snapshot storage may also help in an emergency. Although the page snapshot of the information may not be up-to-date, but a snapshot of the page to find information than in the actual pages much faster, at this time can be encrypted proxy access Google, and then visit its website snapshots to help in an emergency.
Fifth, to hide the identity of
Proxy server is hacking basic knowledge, the hacker's activities, many through a proxy server, such as scanning, spying on the local area network within the machine to carry out infiltration, hacker attacks in general are a lot of transit-class springboard to attack the target machine. To hide the identity and ensure their safety.
Sixth, speed
Increase the download speed to break through the download limit. For instance, some Web site to download the resources to do a thread-IP restrictions, which can be used when the conveyor belt audio-visual, multi-threaded set for each agent to set up a thread. IP restrictions for a breakthrough in the situation very well, as long as a different proxy server, you can download at the same time a number of resources to apply from the WEB and FTP download. But if there is a forum of resources, each user an account and a restricted account a IP, proxy server could not break through on. As an example, here we are, telecommunications users on the movie Web site can not be Unicom, China Unicom users of telecommunications can not be on the film site, as long as the situation of the telecommunications Unicom to find an agent, IP address Unicom is on the line. Unicom, a telecommunications agent to find. Will be able to download movies to their film. Education Network through a proxy server can leave the country without authority or permission to visit a section of the IP-related computer resources.

The proxy server search and verification (2)
It can be said that the proxy server is not very stable, and some perfectly good use of yesterday, today, can not be used, or to a password in order to find out whether the agent or the Free, it is necessary to use "proxy hunter" test function. Deputy hunter the lower right corner of the 8 button, the first "test", and the second is the "full test", we can all 〔〕 test to verify the list of all the agents can use it, you can select from the list One or more proxy address, click 〔〕 test, only to verify whether these agents can be used. After the verification, click on the title of the list "to verify the status," can be used to the proxy server in order to concentrate in front of the list, looking for convenience.
Fourth, how to export and import the results of
If you find a lot of proxy servers, like a friend, you can click on the results of 〔〕 Export button, the selected or all of the agents stored in an address extension. Txt text file (using a proxy hunter 3.0 The attention should be paid, at least when the export should be "setting the contents" under the "type" is also selected, together with export) and then the document to your friends on the trip. Your friends get this document, the result can be used to import 〔〕 button, which will be introduced to address his "hunter agent" list (the use of proxy hunter must pay attention to the 3.0 version, using the results of the introduction, when the pop-up Choose File dialog box at the bottom when it is necessary to "avoid duplication of import items" selected, we will be able to make the list appear to repeat the address).
If you find the Web address of the agent released by the users, how to import these addresses, "Deputy hunter" in it? Here's how:
1, open a text editor (such as built-in Windows Notepad).
2, this format, "Address: @ port type" enter an address, the exclusive address of each party. Note: The ":" and "@" is the punctuation in English, Chinese can not use punctuation. @ HTTP is the type of omission can be as "address: port" without having to write back @ HTTP. Such as:
210.77.125.90:1080 @ SOCKS5
210.62.225.8:3128
200.77.125.146:21 @ FTP
61.173.65.126:3128
211.78.26.35:80
132.162.17.194:21 @ FTP
202.104.141.130:80
218.63.120.31:8080
61.78.60.10:1080 @ SOCKS5
3, to take any of this document preservation, such as proxy.txt.
4, to start deputy hunter, and select "Import results", to find just the proxy.txt edit documents, you can import (Remember to select "Import to avoid duplication of items").
5, just select the Import results, click 〔〕 test, can not be used to be able to clear.
Fourth, how to export and import the results of

The main functions of a proxy server
(1) to set user authentication and billing functions, the user can account for unregistered users the right to Internet access through a proxy server network. And the user's visit, the place to visit, the flow of information to compile the statistics.
(2) user management at different levels, different set of users access to internal or external Internet address filtering, a different set of access rights.
(3) increase in the buffer (Cache), to increase the speed of access, often visit the address to create a buffer zone to greatly improve the efficiency of the popular sites to visit. The proxy server settings are usually a larger hard disk buffer (possibly up to several GB or greater), when the outside world through information, but also to preserve its buffer zone, and then when other users access the same information , Directly in the buffer zone out information to users in order to improve access speed.
(4) Internet connection with the Internet, to act as a firewall (Firewall): since all internal network users to visit the outside world through a proxy server, only one IP address for the map, so outsiders can not directly access the internal network; at the same time can be set up IP address filtering, Restrictions on the internal network to external access.
(5) cost-saving IP: the proxy server to allow the use of a large number of IP address pseudo-saving on-line resources, that is, to use a proxy server to the IP address can reduce the demand for the use of local area network access methods Internet, as if the local area network (LAN) for each A user to apply for an IP address, the cost can be imagined. However, the use of proxy servers, proxy servers can have a legitimate IP address, LAN users can use the other 10 .*.*.* such a private IP address, this can save a lot of IP, to reduce network maintenance costs.
What is HTTP proxy: www for each of the Internet are the familiar, www is used to connect the http request, so we browse the Web, download data (ftp may also have an agreement) that is used http proxy. It is usually bound in a proxy server, and other ports on the 80,3128,8080.
What is a socks proxy: the use of socks agreement is SOCKS proxy server, is a common proxy server. Socks is the bottom of the circuit-level gateway, is DavidKoblas in 1990 developed since then has been on the Internet RFC standards as open standards. Socks are not required to follow specific application of the operating system platform, Socks proxy and application-level proxy, HTTP layer of different agents, Socks proxy simply pass packets without having to be concerned about what kind of application protocol (such as FTP, HTTP and NNTP request) . So, Socks proxy other than the application layer proxy much faster. It is usually binding on the proxy server on port 1080. If you are an enterprise campus network or the Internet, through a firewall or through a proxy server on the Internet access may need to use SOCKS. Under normal circumstances, for dial-up users do not need to use it. Note that the website often used a proxy server is usually devoted to the http proxy, SOCKS, and it is different. As a result, you can visit the website does not mean you can SOCKS visit Internet. Popular firewall or proxy software support SOCKS, but the administrator to open the function. If you are not sure whether you need to SOCKS or whether SOCKS available, contact your network administrator. In order to use the socks, you need to know:
① SOCKS server's IP address
② SOCKS port's services
③ SOCKS the need for user authentication services? If you would like your network administrator to apply for a password and user
Know that the above information, you can fill in this information, "the network configuration", or fill in registration for the first time, you can use a proxy socks.
In practice, can be used as a SOCKS proxy: e-mail and newsgroup software, paging network ICQ, and MIRC chat network uses a proxy server to play the game Lianzhong, and so on a variety of applications among the game.

FAQ: Proxy Server
What is a proxy server?
A Proxy (proxy server) is a server that acts as mediator between the client (the computer of a user) and server (the computer on the other ends of network connection on which the information requested by the user appears for example web server site.) When clients request data from an Internet resource, traffic goes from your web browser/application first through the proxy before it reachs the requested sources and back through the proxy. Then the proxy will transmit the data (information) to you.
Why I need to use a proxy server?
1. Transfer speed improvement. If the file you requested was received before to your proxy server, then proxy server will interrupt this file request and you will receive the file directly from proxy. However need to know, you can got the "speed down" effect. This effect appears when your proxy has long answer time because there is slow connection between you and your proxy server.
2. Security and privacy. Anonymous proxies destroys information about your computer in the requests header. So you can safely surf the net and your information will never be used by hackers and spammers.
3. Sometimes you encounter some problems while accessing to web server (for example, web-chat). You have mistaken while working with some data and / or the server administrator restricted access from your IP. So you can use the anonymous proxy and try to access again.
How can I get fresh proxy server information?
Every proxy server is inclusive of an IP address and a proxy port that is listed next to the address. You can search “free proxy list” on google to get newest proxy servers. Here is a daily updated proxy list I recommend: http://www.aplusproxy.com/proxylist/index.php
How to configure IE 7.0 to use a proxy server?
1. Open Internet Explorer 7.0.
2. Click on the Tools icon from the upper right of the browser and select Internet Options from the menu.
3. Select the Connections tab and click the button for LAN Settings.
4. Click the radio button for Proxy Server. Type the IP number of the proxy In the Address box, and add the port number of the proxy in the Port box.
5. Click the OK button, then OK again.
6. After setting a proxy server, you need to check if that proxy is working. Type www.google.com in your IE7 address bar and see if google index page is loaded for you.
