在Golang net / http中设置服务器软件变量

I'm benchmarking my application with ab -c 100 -n 10000 http://{your ip}:8000/, everything is fine, but being obsessive as I am, I found that while describing the server, it came back with

Server Software:        
Server Hostname:        localhost
Server Port:            1337

Document Path:          /
Document Length:        19 bytes

How do I set the Server Software variable? I can't live with that empty field right there.

Set a Server header. See RFC-2616 section 14.38 and ResponseWriter.Header.

w.Header().Set("Server", "MyServer")
