How can I choose a good proxy server

Safe online, the first step is to choose a secure and fast proxy server as the first level agent. Nowadays, many proxy servers published on many websites are not easy to use, and the speed of use is not ideal. Because we generally use the double proxy encryption method to access the Internet, if the first-level proxy is not easy to use, it will cause login. failure. Therefore, I think that choosing a safe and fast first-level agent is the basis for secure Internet access. This article on how to choose an agent, write my experience, for your reference. Description: Introduce a proxy list to the multiproxy for filtering, and import the filtered list into the browser for manual testing to select a safe and fast proxy. For the specific method of using multiproxy and the proxy list, please refer to the description of "Multiproxy Usage". The role of multiproxy: 1. Use the exhaustive method to quickly filter responsive, anonymous, and fast agents from a large number of proxy servers (proxy server lists). 2. Arrange the responding proxy addresses in automatic order according to their response speed. 3. Convert the domain name to an IP address and determine from the IP address segment which are domestic addresses. (Note that the domestic IP address may be deleted from the proxy list, especially for agents with the highest speed.) 4. Import and export the tested proxy server list for later use by yourself or others. 5. Ability to use multiple agents to simultaneously access a website or directly download a Japanese article. (Network ants and download tools such as flashget are available). (But using this method to access the website or downloading software is not high security, it should be combined with other methods to improve security.) In use, multiproxy can test the speed of the proxy server, but sometimes some agents test quickly, use it and Not ideal, in order to accurately test the status of the agent, you can manually detect the multiproxy filter export agent.
