    // If any custom headers need to be included with the POST, add them

    // Note: An application should never explicitly set the Content-Length header.
    // The Content-Length is automatically computed and added by Chilkat.

    // Here are some examples of custom headers.  

    // Perhaps your particular app needs some sort of custom-computed Authorization header...
    CkHttpW_SetRequestHeader(http,L"Authorization",L"my-custom-computed-auth-value");

    // Another custom header for some hypothetical app:
    CkHttpW_SetRequestHeader(http,L"X-Pass-Timestamp",L"my-custom-computed-timestamp-value");

    // The following "Accept" header may be set, but it really isn't necessary:
    CkHttpW_SetRequestHeader(http,L"Accept",L"application/json");

    jsonText = L"{ some JSON text ... }";

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