(MFC) HTTP Digest-MD5 Authentication Testing with httpbin.org

The URL https://httpbin.org/digest-auth/auth/user/passwd is password protected with user="user" and password="passwd". It requires Digest-MD5 authentication. Chilkat will automatically handle Digest-MD5 authentication as required by the server response. In this case, however, the server will fail the authentication unless a Cookie is included in the request. The cookie can have any name and any value. (Yes, this is ridiculous, and many developers have probably spent countless hours assuming their Digest-MD5 implementations were incorrect.)

#include <CkHttp.h>

void ChilkatSample(void)
    {
    CkString strOut;

    // This example assumes the Chilkat HTTP API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkHttp http;

    http.put_Login("user");
    http.put_Password("passwd");

    // Add a cookie to satisfy httpbin.org's desire for cookies..
    // Otherwise, it will fail the perfectly valid Digest-MD5 authentication.
    http.SetRequestHeader("Cookie","something=\"something\"");

    const char *strResponse = http.quickGetStr("https://httpbin.org/digest-auth/auth/user/passwd");
    if (http.get_LastMethodSuccess() == false) {
        strOut.append(http.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    strOut.append(strResponse);
    strOut.append("\r\n");

    int status = http.get_LastStatus();
    strOut.append("response status code = ");
    strOut.appendInt(status);
    strOut.append("\r\n");

    // The output of this program is:
    //
