    let http = CkoHttp()!

    // 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 will delete the file named "penguins2.jpg" 
    // which is located in the "/Documents" folder.

    let req = CkoHttpRequest()!
    req.httpVerb = "POST"
    req.path = "/_api/web/GetFileByServerRelativeUrl('/Documents/penguins2.jpg')"

    // We need to add a form digest value in the X-RequestDigest header field.
    // See this example for details on
    // how to get (and cache) a form digest value
    req.addHeader("X-RequestDigest", value: "SHAREPOINT_FORM_DIGEST")

    // Add additional required headers.
    req.addHeader("IF-MATCH", value: "*")
    req.addHeader("X-HTTP-Method", value: "DELETE")

    // Send the POST using https (TLS). Port 443 is the default port for https.

    var resp: CkoHttpResponse? = http.synchronousRequest("SHAREPOINT_HTTPS_DOMAIN", port: 443, ssl: bUseTls, req: req)
    if http.lastMethodSuccess != true {
        print("\(http.lastErrorText!)")
        return
    }

    // If failed, the response body contains XML 
    let xml = CkoXml()!
    xml.load(resp!.bodyStr)

    if resp!.statusCode.intValue != 200 {
        print("Response status code = \(resp!.statusCode.intValue)")
        print("\(xml.getXml()!)")

        // For example, if the file did not exist, this would be the XML response:
        // <?xml version="1.0" encoding="utf-8" ?>
        // <m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
        //     <m:code>-2146232832, Microsoft.SharePoint.SPException</m:code>
        //     <m:message xml:lang="en-US">The file /Documents/penguins2.jpg does not exist.</m:message>
        // </m:error>
        // 

        print("Failed")
        resp = nil
