Question

I am trying to set a gorilla session and then retreive the value again. I am doing the following just as a test.

//create session and store in http Cookies
session, err := store.Get(req, "session")
if err != nil {
    errCode = http.StatusInternalServerError
    return
}

//save a value
session.Values["user_id"] = userTuple.UserId
err = session.Save(req, w)
if err != nil {
    errCode = http.StatusInternalServerError
    return
}

//try to get the same session that was just created
nr := http.Request{Header: w.Header()}
session, err = store.Get(&nr, "session")
if err != nil {
    errCode = http.StatusInternalServerError
    return
} else if session.IsNew {
    log.Println("New session created instead of old one.")
}

This is a snippet out of a larger HTTP handler. But the relavent parts are posted and the the second call to store.Get() is not returning an existing session, but a brand new one. Hence, when the handler this code is in is executed, the log statements is printed to console.

Why am I getting a new session in this case instead of the one I had already created and saved?

I feel like I already answered this question. You are misusing this pkg. Behind the scenes the context package is used to store state for a request, by creating a new, incomplete http.Request, the context package returns an empty state with no session info.
