Forcefully Closing HTTP Connections in Go

When a user terminates a download or disconnects their network, it's crucial to gracefully handle the termination of the HTTP connection on the server side. This prevents system resources from being consumed unnecessarily. In this article, we'll explore how to forcefully close HTTP connections in Go.

Scenario and Issue:

Consider the following code snippet, which downloads a file from a server and streams it back to the user:

resp, httpErr := http.Get(url.String())
if httpErr != nil {
    fmt.Fprintln(w, "Http Request Failed :", httpErr.Error())
    return
}
