Sorry, I made a mistake when copy paste :)
Actually we can assume above code as
go func() {
...
}
Because I want to reference of w variable which is the type of
http.ResponseWrite.
My actual problem is w.wr is nil inside go routine. I can post the code
today but I can not access the code right now.
