gorilla/sessions的使用,求指教

gorilla/session的使用求指教..以下为官方example

import (
    "net/http"
    "github.com/gorilla/sessions"
)

var store = sessions.NewCookieStore([]byte("something-very-secret"))

func MyHandler(w http.ResponseWriter, r *http.Request) {
    // Get a session. We're ignoring the error resulted from decoding an
    // existing session: Get() always returns a session, even if empty.
    session, _ := store.Get(r, "session-name")
    // Set some session values.
    session.Values["foo"] = "bar"
    session.Values[42] = 43
    // Save it.
    session.Save(r, w)
}

代码里something-very-secret应该就是session的加密码..而store.Get(r,"session-name")这个session-name是不是我们常说的sessionid?
