In-depth analysis of the differences between system agents and global agents

In network communication, proxy servers play an important role. They can transfer client requests and server responses and implement various functions, such as load balancing, anonymity protection, cache acceleration, etc. According to different application scenarios and configuration methods, proxy servers can be divided into two categories: system proxy and global proxy. This article will explore the difference between the two in depth to help readers understand their respective characteristics, applicable scenarios and configuration methods, and briefly mention 98IP proxy as an option for proxy service.

I. Basic concepts of system proxy and global proxy

1.1 System proxy

System proxy, also known as application proxy or local proxy, refers to proxy settings configured only in specific applications or system services. This proxy method allows users to set different proxy servers for different applications to achieve refined network access control.

• ​Features​:
• ​Flexibility​: You can set different proxy rules for different applications to meet diverse network needs.
• ​Independence​: The proxy settings of one application will not affect other applications.
• ​Complex configuration​: You need to configure the proxy for each application separately, which has high management costs.
  
  

1.2 Global Proxy

Global proxy, also known as system-level proxy or overall proxy, refers to a proxy server set up at the level of the entire operating system. Once configured, all network requests passing through the operating system will be forwarded through the specified proxy server.

• ​Features​:
• ​Uniformity​: All network requests go through the same proxy server, which is convenient for unified management.
• ​Convenience​: No need to configure each application separately, saving time.
• ​Potential risks​: All network traffic passes through the proxy, which may increase latency, and once there is a problem with the proxy service, it will affect all network access.
  
  

II. Application scenarios and selection strategies

2.1 Application scenarios of system proxy

• ​Specific applications need to access foreign resources​: For example, some scientific research software or professional tools need to access foreign databases or APIs through specific proxy servers.
• ​Privacy protection requirements​: Configure anonymous proxies for certain sensitive applications to protect user privacy.
• ​Network optimization​: Improve network access speed by configuring high-speed proxy servers for specific applications.
  
  

2.2 Application scenarios of global proxy

• ​International network access​: For users who need to frequently access foreign websites or services, global proxy can simplify configuration and improve access efficiency.
• ​Network security​: Through global proxy, all network requests can be filtered and monitored to improve network security protection capabilities.
• ​Unified policy management​: For large enterprises or educational institutions, global proxy can easily manage network access policies in a unified manner.
  
  

2.3 Selection Strategy

When choosing between system proxy and global proxy, the following factors should be considered:

• ​User needs​: Choose the most appropriate proxy method based on specific application scenarios and needs.
• ​Network performance​: Evaluate the performance of the proxy server to ensure that it can meet the speed and quality requirements of network access.
• ​Management cost​: Consider the complexity of proxy configuration and management, and choose a solution that is easy to maintain and manage.
  
  

III. Configuration methods and precautions

3.1 System proxy configuration method

In Windows, you can configure it through "Settings" -> "Network and Internet" -> "Proxy". For macOS and Linux systems, you can usually configure it through system preferences or command line tools. In addition, many applications also provide built-in proxy settings options.

3.2 Global proxy configuration method

Global proxy configuration usually needs to be performed in the network settings of the operating system, and the specific method varies depending on the operating system. In Windows, you can configure it through "Internet Options" -> "Connections" -> "LAN Settings". In macOS, you can set it through "System Preferences" -> "Network" -> "Advanced" -> "Proxy".

​Notes​:

• ​Proxy server selection​: Choose a reliable and high-speed proxy server, such as 98IP Proxy, to ensure the stability and security of network access.
• ​Privacy protection​: When using a proxy server, pay attention to protecting personal privacy and data security to avoid sensitive information leakage.
• ​Compliance​: Ensure that the use of the proxy server complies with local laws and regulations and the regulations of the network service provider.
  
  

IV. Summary and Development

System proxy and global proxy are two common proxy methods, each with its own advantages and disadvantages and applicable scenarios. When choosing and using, you should consider factors such as actual needs, network performance and management costs. With the continuous development of network technology, the functions of proxy servers will be richer and more complete, providing users with a more convenient and efficient network access experience. At the same time, choosing a reliable proxy service provider (such as 98IP Proxy) is also an important guarantee to ensure the quality and security of network access.
