This article shows you how to buffer the configuration of Nginx reverse proxy and server. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Nginx reverse proxy about the configuration of the back-end server. For the majority of network administrators, nginx reverse proxy is a compulsory course. Next, let's take a look at the relevant content. There are three back-end services, one for web content, one for forums, and one for documents.

When a request comes, the nginx proxy server looks at the url and directs the request to the corresponding server. This configuration also buffers the contents of the file service, but the contents of the forum and data downloads are not cached. This configuration also uses compression to better save memory.
