Listing 5-7:Cookie-Setting Code from the Gmail Login

function SetGmailCookie(name, value) {

document.cookie = name + “=” + value +

“;path=/;domain=google.com”;

}

// This is called when the user logs in to gmail.

// We set a GMAIL_LOGIN2 cookie with the initial timings.

// The first letter “T” in the cookie value means that the

login is not

// completed yet. The main JS will complete logging the

timings and update

// the GMAIL_LOGIN2 cookie. See main.js

function lg() {

var now = (new Date()).getTime();

// use start_time as a place holder for login_box_time until

we’ve

// completely rolled out html-only login

var cookie = “T” + start_time + “/” + start_time + “/” +

now;
