Demonstrates how to persist incoming cookies to XML files and automatically re-send in subsesquent HTTP requests. Chilkat2 Java

import com.chilkatsoft.chilkat2.Http;

public class ChilkatExample {

    public static void main(String[] args) {
        // This example assumes the Chilkat API to have been previously unlocked.
        // See Global Unlock Sample for sample code.

        Http http = new Http();

        // To save cookies to XML files (per domain) in a specific
        // directory, set the CookieDir property (the directory must
        // already exist and be writeable by the caller).  Also,
        // set the SaveCookies property:
        http.setCookieDir("/cookieDir");
        http.setSaveCookies(true);

        // Any methods that do a GET, POST, etc. will save cookies
        // to the CookieDir:
        String html = http.quickGetStr("https://www.paypal.com/");

        // After running this code, a "paypal_com.xml" file should appear
        // in /cookieDir.

        // It's content will look something like this:

        // <cookies>
        //     <cookie key=".paypal.com,/" v="0" secure="yes">
        //         <navcmd>_home-general</navcmd>
        //         <HttpOnly />
        //         <cwrClyrK4LoCV1fydGbAxiNL6iG>9cz...</cwrClyrK4LoCV1fydGbAxiNL6iG>
        //     </cookie>
        // </cookies>

        // To cause cached cookies to be sent with
        // subsequent HTTP requests, set the SendCookies
        // property = true.
        http.setSendCookies(true);

        // If another HTTP request is sent, the cookies should
        // be added:
        html = http.quickGetStr("https://www.paypal.com/");

        // Check the LastHeader property to see the MIME header
        // of the last HTTP request sent.
        // The "Cookie" header field should be present.
        System.out.println("--- LastHeader ---");
        System.out.println(http.getLastHeader());
