UploadSettings.ChunkSize Property

Gets or sets a maximium allowed size of binary data (in bytes) uploaded within a POST request.

Namespace: Aurigma.ImageUploaderFlash
Assembly: Aurigma.ImageUploaderFlash (in Aurigma.ImageUploaderFlash.dll)


Visual Basic
Public Property ChunkSize As Integer
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.

Default value is 0.


When this property is greater than 0, Image Uploader Flash 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, Image Uploader Flash 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 Image Uploader Flash 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.
