The default timeout is `60` seconds, function prototype:

	SetTimeout(connectTimeout, readWriteTimeout time.Duration)

Exmaple:

	// GET
	httplib.Get("http://beego.me/").SetTimeout(100 * time.Second, 30 * time.Second)
	
	// POST
	httplib.Post("http://beego.me/").SetTimeout(100 * time.Second, 30 * time.Second)


## Debug

If you want to debug the request info, set the debug on

	httplib.Get("http://beego.me/").Debug(true)
	
## Set HTTP Basic Auth

	str, err := Get("http://beego.me/").SetBasicAuth("user", "passwd").String()
	if err != nil {
        	// error
	}
	fmt.Println(str)
	
## Set HTTPS

If request url is https, You can set the client support TSL:

	httplib.SetTLSClientConfig(&tls.Config{InsecureSkipVerify: true})
	
More info about the `tls.Config` please visit http://golang.org/pkg/crypto/tls/#Config	

## Set HTTP Version

	req := httplib.Post("http://beego.me/")
	req.Param("username","astaxie")
	req.PostFile("uploadfile1", "httplib.pdf")
	str, err := req.String()
	if err != nil {
