1. Like Apache, they are both HTTP server software and adopt Modular Design for function implementation. They all support common language interfaces. At the same time, they also support forward and reverse proxies, virtual hosts, and URL rewriting,CompressionTransmission, SSL encrypted transmission, and so on. However, in terms of execution efficiency, nginx processes faster and consumes less memory resources. In addition, nginx also supports fcgi, wh
