Connection not closed properly

[pacbeckh]

We're using go's "net/http" client to send http requests to the stub.
When sending multiple POST requests to the openmock http server the client fails with an EOF error.

After investigating further we noticed that the this error occurs if the server closed the connection without noticing the client.

To reproduce this I created a simple stub:

- key: mystub
  kind: Behavior
  expect:
    http:
      method: POST
      path: /
  actions:
    - reply_http:
        status_code: 200
        body: somepostresponse

And a small go test

import (
	"fmt"
	"io/ioutil"
	"net/http"
	"strconv"
	"strings"
	"testing"
)

func TestPost(t *testing.T) {
	for i := 0; i < 20; i++ {
		if err := sendRequest(i); err != nil {
			panic(fmt.Sprintf("sending request %d failed because of %v", i, err))
		}
	}
}

func sendRequest(i int) error {
	resp, err := http.Post("http://localhost:9091", "text", strings.NewReader("request "+strconv.Itoa(i)))
	if err != nil {
		panic(err)
	}

	defer resp.Body.Close()
	respBody, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		panic(err)
	}

	println(fmt.Sprintf("got response %s for request %d", string(respBody), i))
	return nil
}

Our current workaround is to add the "connection: close" header to each stubbed request to signal the http client that it shouldn't reuse the connection, but is there any way this can be solved in the openmock server?
If not, then this at least might be useful for the next person using go and running into this issue.

Thanks!
