Re: Problem with Upload Error handling

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

there is no cancel upload command the server can send, so when the upload is too big, the server closes the connection. this means the server can not send back a response, and the browser displays failed request error (dns in IE)

Problem with Upload Error handling

When the user uploads the file greater than the length specified in web.config/machine.config, I always see the DNS Error page eventhough I have handled the error Page_Error Event.

And this is my code in Page_Error event,


Private Sub Page_Error(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Error

Dim ex As Exception = Server.GetLastError.GetBaseException

If TypeOf (ex) Is HttpException Then

Dim oEx As HttpException = CType(ex, HttpException)
If oEx.ErrorCode = -2147467259 Then
Dim ErrorLabel As New Label
ErrorLabel.ForeColor = System.Drawing.Color.Red
ErrorLabel.Text = "La dimensione del file supera la dimensione massima consentita di 4MB"
Dim oCell As New HtmlTableCell
oCell.Controls.Add(ErrorLabel)
trUpload.Cells.Add(oCell)
Server.ClearError()
Response.ClearHeaders()
Response.Status = "200 OK"
Response.End()
Else
Throw New ApplicationException(oEx.Message, oEx)
End If
Else
Throw New ApplicationException(ex.Message, ex)
End If

End Sub


I tried to set later just to get rid of DNS Error

Response.Status = "200 OK"
Response.End()

But in vain.

Can anyone shed some light on this? Why so Response.Status does not work?

TIA,
Holy
