**Deprecated.**. HTTP/2 and many HTTP/1.1 servers don't support this; we recommend leaving it set to false (default).
This property indicates whether the UnityWebRequest should employ the HTTP/1.1 chunked-transfer encoding method, which allows the system to send partial data and be prompted by the server for more data with a 100/Continue HTTP response. This property cannot be changed after calling Send.
Note: On WebGL build targets, this setting is ignored. Instead, the web browser handles protocol negotiations.
Default value: false
