    ;  sent.  (These headers are harmless, and shouldn't need to
    ;  be suppressed, but just in case...)

    CkHttp::setCkAcceptLanguage(http, "")

    ;  Suppress the Accept-Encoding header by disallowing
    ;  a gzip response:
    CkHttp::setCkAllowGzip(http, 0)

    ;  If a Cookie needs to be added, it may be added by calling
    ;  AddQuickHeader:
    success = CkHttp::ckAddQuickHeader(http,"Cookie","JSESSIONID=1234")

    ;  Add the Content-Encoding: identity header.
    success = CkHttp::ckAddQuickHeader(http,"Content-Encoding","identity")

    ;  Modify the default "Accept" header:
    CkHttp::setCkAccept(http, "application/jsonrequest")

    ;  To use SSL/TLS, simply use "https://" in the URL.

    ;  IMPORTANT: Make sure to change the URL, JSON text,
    ;  and other data items to your own values.  The URL used
    ;  in this example will not actually work.
