property SendChunked: boolean; default False;
The SendChunked property gets or sets the value that indicates whether to send data in segments to the Internet resource.
When SendChunked is True, the request sends data to the Internet resource in segments. The Internet resource must support receiving chunked data.
If you change the SendChunked property after the request has been started by calling the GetResponse method, the HttpException is raised.
If SendChunked is set to True, TScHttpWebRequest checks whether the RequestStream property or the OnGetNextChunkData event handler is set, and if both values are nil, the HttpException is raised.
The default value is False.
