Persist Cookies to XML Files and Auto Re-Send

See more HTTP Examples

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

#include <CkHttp.h>

void ChilkatSample(void)
    {
    //  This example assumes the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    CkHttp 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.put_CookieDir("/cookieDir");
    http.put_SaveCookies(true);

    //  Any methods that do a GET, POST, etc. will save cookies
    //  to the CookieDir:
    const char *html = 0;
    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.put_SendCookies(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.
    std::cout << "--- LastHeader ---" << "\r\n";
    std::cout << http.lastHeader() << "\r\n";
