    // The following comments apply to SharePoint Windows classic authentication.
    // -------------------------------------------------------------------------
    // For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
    // The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
    // The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
    // Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
    // for example, "chilkat" instead of "chilkat@mycompany.com"

    var http = new chilkat.Http();

    // If SharePoint Windows classic authentication is used, then set the 
    // Login, Password, LoginDomain, and NtlmAuth properties.
    http.Login = "SHAREPOINT_USERNAME";
    http.Password = "SHAREPOINT_PASSWORD";
    http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN";
    http.NtlmAuth = true;

    // -------------------------------------------------------------------------
    // The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    // If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    // establish the cookie as shown at SharePoint Online Authentication
    // -------------------------------------------------------------------------

    // This example downloads the file named "Domain Name created for Exchange.docx"

    // Note: I was initially confused by the "$value" part of the URL. 
    // When I see something like $value, I immediately think that it's some sort of
    // variable or placeholder to be replaced with an actual value.  In this case,
    // the "$value" is literally part of the URL.  It's not replace with anything.

    var url = "https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents')/Files('Domain Name created for Exchange.docx')/$value";
    var localFilePath = "qa_output/x.docx";

    var success = http.Download(url,localFilePath);
    if (success !== true) {
        console.log(http.LastErrorText);
        return;
    }

    console.log("File successfully downloaded from SharePoint.");
