package app 

import (
    "http" 
    "appengine" 
    "appengine/urlfetch" 
    "bytes" 
    "fmt" 
) 

func init() { 
    http.HandleFunc("/post", post) 
} 

func post(w http.ResponseWriter, r *http.Request) { 
    c := appengine.NewContext(r) 
    bs := []byte{1,2,3} 
    buf := bytes.NewBuffer(bs) 
    client := http.Client{Transport: &urlfetch.Transport{Context:c}} 
    if _, err := client.Post("http://localhost:8080/", "application/octet-stream", buf); err != nil { 
     fmt.Println(err) 
    } 
}
