Example of a HTTP server in Go to handle GET requests from memory
Nov 03 '21

This an example of a simple HTTP server written in Go. It handles GET requests, matches the URL path to a function, and returns a HTML response from a global variable.

We are using the small FastHTTP library that adds a worker pool of goroutines for faster response time. 

package main

import (
        "github.com/valyala/fasthttp"
)

var x1 = `<!DOCTYPE html>
<html lang="en">
<head>
<title>This is a Website</title>
</head>
<body>
Xor The World!
</body>
</html>`

func main() {

h0 := func(ctx *fasthttp.RequestCtx) {

switch string(ctx.Path()) {

        case "/":
           ctx.SetContentType("text/html; charset=utf8")
           ctx.WriteString(x1)

        default:
           ctx.SetStatusCode(404)

                         }
}

s := &fasthttp.Server{
       Name: "XOR Server",
       Handler: h0,
}
        s.ListenAndServe(":80")
        }

You can compile the program for any OS, and run it on the background. In Linux for example you will run it as  nohup ./server > /dev/null 2>&1 &  where standard output from the server log gets redirected to dev/null.
