Is the http proxy closed automatically?

HTTP proxy refers to the use of a proxy server to allow network users to access external websites. The proxy server is a server between the browser and the web server. It is automatically activated if necessary. Most people do not use that function and it is turned off by default. of. If it is turned on, the Internet speed will be extremely slow. Selecting Automatic will basically affect the Internet speed. [Recommended tutorial: HTTP video tutorial]

## 1. HTTP protocol:

1. The protocol is the Hypertext Transfer Protocol, which is a very simple communication protocol that is most widely used for upstream information transmission on the Internet. Some LANs have restrictions on protocols and only allow users to access external websites through the HTTP protocol.

2. Currently the HTTP function supports "direct connection" and connection through "HTTP proxy". Which form to choose depends on the specific conditions of the local area network (or other Internet environment) where the user is located.

3. Simply put, if the user's local area network does not have any proxy server, select "Direct Connection" to achieve QQ connectivity; and if the user's local area network has a proxy server, you must select "Through HTTP proxy" and fill in the proxy server address, port and other details of the local area network to achieve QQ connectivity.

4. Because the LAN configuration environment is relatively complex, you can first use the "Test" function to determine whether QQ connectivity can be achieved through the HTTP function.

2. The main functions are:

1. Break through your own IP access restrictions and access foreign sites. For example, Internet users such as Education Network and 169 Network can access foreign websites through proxies.

2. To access internal resources of some units or groups, such as FTP of a certain university (provided that the proxy address is within the allowed access range of the resource), use the address segment within the education network for free

The proxy server can be used for various FTP download and upload services open to the education network, as well as various data query and sharing services.

3. Break through China Telecom's IP blockade: China Telecom users have restricted access to many websites. This restriction is artificial, and different Serves block addresses differently. Therefore, if you cannot access it, you can try a foreign proxy server.

4. Improve access speed: Usually proxy servers set up a larger hard disk buffer. When external information passes through, it is also saved in the buffer. When other users access the same information again, When receiving information, the information is directly taken out from the buffer and passed to the user to improve access speed.

5. Hide real IP: Internet users can also use this method to hide their IP and avoid attacks.
