Details

The Upload WebApi2 Controller is what handles the Flow.js upload. It uses the FlowUploadProcessor in /Services to conduct the upload. The class is thread safe and has been tested with 4 simultaneous uploads with multiple threads, and implements the GET Testing of individual chunks.

The important part of this implementation is the custom FlowMultiplartFormDataStreamProvider.cs that handles the actual streaming of files to disk. When it gets to the file part of the HTTP Body it retrieves the FlowMetaData from the previous content and uses that data to save the chunk to the appropriate file.
