about http hijacking and keep-alive

Question

i use

resp, err := http.Get("http://example.com/")

get a http.Response, and i want to exactly write to a http handler, but only http.ResponseWriter, so i hijack it.

...
webConn, webBuf, err := hj.Hijack()
if err != nil {
    // handle error
}
defer webConn.Close()

// Write resp
resp.Write(webBuf)
...

Write raw request

But When i hijack, http connection can't reuse (keep-alive), so it slow.

How to solve?

Thanks! Sorry for my pool English.

update 12/9 keepalive keepalive2 keep-alive, It keep two tcp connection, and can reuse.

nokeepalive nokeepalive2 but when i hijack, and conn.Close(), It can't reuse old connection, so it create a new tcp connection when i each refresh.
