Helper object for UnityWebRequests. Manages the buffering and transmission of body data during HTTP requests.
When attached to a UnityWebRequest, an UploadHandler object handles all information regarding the buffering and transmission of body data during an HTTP request. By placing data in an UploadHandler and attaching it to a UnityWebRequest, the UnityWebRequest is implicitly instructed to transmit the UploadHandler's data to the remote server. The data will always be delivered as HTTP request body data.
UploadHandler is a base class and cannot be directly instantiated. Currently, two types of UploadHandlers are available: UploadHandlerRaw and UploadHandlerFile.
Additional resources: UnityWebRequest, UploadHandlerRaw, UploadHandlerFile.
