Large File Upload Using HttpHandler or HttpModule? - asp.net

Question

I have a webform application. It required to be able to upload large file (100MB). I intended to use httpHandler and httpModule to split the file to chunk.
I also had a look at http://forums.asp.net/t/55127.aspx
But it is a very old post and I've seen some example on the internet using httpHandler.
e.g. http://silverlightfileupld.codeplex.com/
I'm not sure httpModule is still better then httpHandler.
Since httpModule apples to the request of the whole application, and I just want it apply to specify page.
Can anybody explain the shortcoming of httpHandler for large file upload clearly (if it has)?
If you know a good example without flash/silverlight , could you post the link here? thx
Edit: Would Like to see some Source Code example.

Answer 1

Why not try plupload which has lot of features with many fallbacks and here how it is done.
This is the http handler code:
Imports System
Imports System.IO
Imports System.Web
Public Class upload : Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim chunk As Integer = If(context.Request("chunk") IsNot Nothing, Integer.Parse(context.Request("chunk")), 0)
Dim fileName As String = If(context.Request("name") IsNot Nothing, context.Request("name"), String.Empty)
Dim fileUpload As HttpPostedFile = context.Request.Files(0)
Dim uploadPath = context.Server.MapPath("~/uploads")
Using fs = New FileStream(Path.Combine(uploadPath, fileName), If(chunk = 0, FileMode.Create, FileMode.Append))
Dim buffer = New Byte(fileUpload.InputStream.Length - 1) {}
fileUpload.InputStream.Read(buffer, 0, buffer.Length)
fs.Write(buffer, 0, buffer.Length)
End Using
context.Response.ContentType = "text/plain"
context.Response.Write("Success")
End Sub
Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End Property
End Class
