    // 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.

    // Do not save cookies to files, just keep them in memory.
