Large File Upload Using HttpHandler or HttpModule?

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.

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
