This lesson presents a simple web server developed in Go in order to better understand the principles behind such applications.

Note: Although a web server programmed in Go can do many things efficiently and securely if what we really need is a powerful web server that supports modules, multiple websites, and virtual hosts, then we would be better off using a web server, such as Apache, Nginx, or Caddy, that is written in Go.

We might ask why the presented web server uses HTTP instead of secure HTTP (HTTPS). The answer to this question is simple: most Go web servers are deployed as Docker images and are hidden behind web servers such as Caddy and Nginx that provide the secure HTTP operation part using the appropriate security credentials. It does not make any sense to use the secure HTTP protocol along with the required security credentials without knowing how and under which domain name the application is going to be deployed. This is a common practice in microservices as well as regular web applications that are deployed in Docker images.
