first save the HTML file, with a ready-made HTTP Server software, to receive user requests, from the file to read HTML, return.If you want to generate HTML dynamically, you need to implement the above steps yourself. However, accepting HTTP requests, parsing HTTP requests, and sending HTTP responses are all menial jobs, and if we're writing these underlying code ourselves, it's going to take months to read the HTTP specification before we start writing Dynamic HTML.The correct approach is that
