Tag: http server

It took me a minute or two to figure out why, while doing some experiments, for the following built-in HTTP server use case, the handler was called two times, and so printing the log message two times.

package main

import (
       "log"
       "net/http"
)

func main() {
       http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
              log.Println("call")
       })

       http.ListenAndServe(":8800", nil)
}

The path “/” catches all requests, thus it catches the “/favicon.ico” request sent by the browser. So I’ve just used another path.
