In this issue, the editor will bring you about whether the CVM can act as a http proxy. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

As long as you know the corresponding code technology, it is possible. To use a CVM as a http proxy, you must first purchase a CVM from the service provider. Usually using a proxy server has the following functions.

Safety filtering

For security, users are not allowed to contact the real server directly. Any access request must first go to the proxy server for authentication, filtering and other security operations. Only qualified requests will be forwarded to the real server, and only the IP in the IP whitelist can be accessed.

Content caching

When the number of visits is increasing, the website server needs to process each request, which is under great pressure. according to the principle of local accessibility, many of the requests must be repeated, and the website server does the repetitive work.

The proxy server caches some commonly used content to himself, and the user's request comes to the proxy server first. He sees if he has any content that the user needs, returns it directly to the user, and gives it to the website server to deal with when it is not available. This is equivalent to having an assistant on the website server, which helps him deal with a lot of repetitive work and reduces the pressure.

Load balancing

When the traffic is getting larger and larger, a website server can no longer handle it, and N servers need to be added, so when the user requests, a proxy server needs to be added in front of the N servers as a load balancer.

The user sends the request to the load balancer first, and he thinks about who the request should be handed over to, and then forwards it, so that the N servers can process the request in a balanced manner.

The above is whether the CVM shared by the editor can be used as a http proxy. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
