Reusing http connections in Go

Question

I'm currently struggling to find a way to reuse connections when making HTTP posts in Go.

I've created a transport and client like so:

// Create a new transport and HTTP client
tr := &http.Transport{}
client := &http.Client{Transport: tr}

I'm then passing this client pointer into a goroutine which is making multiple posts to the same endpoint like so:

r, err := client.Post(url, "application/json", post)

Looking at netstat this appears to be resulting in a new connection for every post resulting in a large number of concurrent connections being open.

What is the correct way to reuse connections in this case?
