This code displays 2 "successfull Operation!!" but when I add /home (http.HandleFunc("/home", foo)), it doesn't. I want to know why it displays "successfull Operation!!" twice. Thank you in advance.
Because modern browsers send an extra request for /favicon.ico which is also handled in your / request handler.
If you ping your server with curl for example, you'll see only one request being sent:
curl localhost:3000
