public int ChunkSize { get; set; }

Property Value

Type: System..::..Int32

The number of bytes allowed to upload within a request. When this value is 0, converted file uploaded entirely in accordiance with FilesPerPackage and UploadConverterOutputSeparately properties.

Default value is 0.


When this property is greater than 0, HTML5/Flash Uploader adds converted files and metadata to a POST request until the request length exceeds ChunkSize + metadata size bytes. If the last added file does not meet the chunk size limitation, HTML5/Flash Uploader adds just a portion of this file to complete this chunk. The remaining portion will be added at the beginning of the next chunk. Each chunk is submitted to a server as a separate request. It gives a number of benefits: makes each request compartible with maximum POST request length limitation and allows resuming partially uploaded files.


When you turn this mode on, it is highly recommended to use HTML5/Flash Uploader ASP.NET to handle upload on the server side. This wrapper automatically bundles pieces of one file, uploaded in separated chunks, and provides an access to this file as if it was uploaded entirely.
