Differences and connections between proxies and global proxies

In the Internet domain, proxies and global proxies are two common concepts that play an important role in network communication. Although they both involve communicating on behalf of other devices or services, they have different characteristics in terms of specific functions and usage scenarios.

代理是指一个代表客户端与服务器进行通信的中间服务。当客户端发送请求时，代理将其接收并转发给目标服务器，然后将服务器的响应返回给客户端。代理可以对请求和响应进行修改或过滤，实现对网络通信的控制和代理ip。

Global proxy, on the other hand, is a system-level proxy setting that acts on the entire network communication environment. By setting the global proxy, users can route all network traffic to the specified proxy server, thus realizing the proxy service for the whole network.

Comparison of the differences between proxies and global proxies

Functionally, proxies usually forward and process requests for specific requests, while global proxies proxy the entire network traffic. This leads to differences in their usage scenarios and configurations.

对于代理来说，它通常被应用在需要对特定请求进行控制或代理ip的场景下。比如，Web代理可以对特定网站的请求进行缓存，以加快用户的访问速度；透明代理可以对网络流量进行监控和过滤，实现对网络安全的保护。而全局代理则更多地被用于需要整个网络环境都通过统一代理进行访问的场景，比如企业内部网络的统一代理设置，或者在一些特殊的网络环境中进行代理访问。

In terms of configuration, proxies usually need to be set up in the client or application to enable proxy forwarding of specific requests, while global proxies need to be set up in the operating system or network device to ensure that traffic from the entire network environment passes through the specified proxy server.

In general, proxy and global proxy are both intermediate forwarding services for network communications in terms of implementation, but their functions and usage scenarios are significantly different. Understanding their differences and connections will help you choose the right proxy to improve the efficiency and security of network communication.
