Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

var http = new CkHttp();

http.SaveCookies = true;
http.CookieDir = "c:/temp/cookie_cache";
// For this initial request, we are not sending cookies.
// We are starting a new (cookie) session and saving the cookies we receive.
http.SendCookies = false;

// Do a request that establishes and saves cookies in files in the cookie directory.
var html = http.QuickGetStr("https://google.com/");

// Examine the LastResponseHeader to see the cookies that were received:
console.log(http.LastResponseHeader);
console.log("----------------------------------");

// We can see the following Set-Cookie response header fields:

// Set-Cookie: AEC=AVh_V2h-fsL2-****; expires=Mon, 23-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; Secure; HttpOnly; SameSite=lax
// Set-Cookie: NID=525=XC_cL****Hn7-WONX; expires=Thu, 26-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; HttpOnly

// The following file was created:  c:/temp/cookie_cache/google_com.xml

// Examine the cookies received in the above request.
console.log(http.GetCookieXml("google.com"));
console.log("----------------------------------");

// Sample output.

// <?xml version="1.0" encoding="utf-8"?>
// <cookies>
//     <cookie key=".google.com,/,AEC" v="0" expire="Mon, 23-Feb-2026 19:05:20 GMT" secure="yes">
//         <AEC>AVh_V2gL8QzTdFGYq6_rS6ktBfqm8WNG3pzHxS2nTZD5i23dRBau2c4ZRA</AEC>
//     </cookie>
//     <cookie key=".google.com,/,NID" v="0" expire="Thu, 26-Feb-2026 19:05:20 GMT">
//         <NID>525=SuLcnaSkFqF4Jz_jLEq4kt_f3MY2Xro1VDoVzLKvp8XHcW2UHuLKJSr55iDeW0NiRIPXoAwJWF1-YNl29unX2xfhEWsS5BhbuK_2DXdD9cTOmn5BSENMhZasxeJ71mEP2PQRMXBndqnl41DhblC2jjdac_so4TESIll1B0GCVe9wRFjqI6DTZItRCj61BHmr1_RAQi0_jrh_ihn6KYtIFEY7</NID>
//     </cookie>
// </cookies>

// -------------------------------------------------------------------------------------------
// Let's say we want to continue with the session at some later time with a new HTTP object.
// One way to do it is to simply set the same cookie properties:
var httpB = new CkHttp();

httpB.SaveCookies = true;
httpB.CookieDir = "c:/temp/cookie_cache";
httpB.SendCookies = true;

// The cookies from the cache are sent.
html = httpB.QuickGetStr("https://google.com/");

// Examine the LastHeader to see the contents of the Cookie header field.
console.log(httpB.LastHeader);
console.log("----------------------------------");

// -------------------------------------------------------------------------------------------
// Another way to do it is to explicitly load the cookies from XML
// and set the cookies for the particular domain.

var httpC = new CkHttp();

httpC.SaveCookies = true;
// Do not save cookies to files, just keep them in memory.
httpC.CookieDir = "memory";
httpC.SendCookies = true;

var sbCookiesXml = new CkStringBuilder();
success = sbCookiesXml.LoadFile("c:/temp/cookie_cache/google_com.xml","utf-8");
if (success == false) {
    console.log(sbCookiesXml.LastErrorText);
    return;
}

success = httpC.SetCookieXml("google.com",sbCookiesXml.GetAsString());
if (success == false) {
    console.log(httpC.LastErrorText);
    return;
}

html = httpC.QuickGetStr("https://google.com/");

// Examine the LastHeader to see the contents of the Cookie header field.
console.log(httpC.LastHeader);
