    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    req = CkHttpRequest_Create();

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

    // 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...
    CkHttp_SetRequestHeader(http,"Authorization","my-custom-computed-auth-value");

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

    // We don't need to set the Content-Type header, becaue it is automatically set by Chilkat
    // in the PostJson2 call below.

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

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

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

    resp = CkHttp_PostJson2(http,"http://www.someserver.com/someJsonEndpoint","application/json",jsonText);
