Get http error codes

[gunyan]

Is there a way to get the http error code?

I use the following code in my global asax.vb to write entries to the event log and would also like to send the error code(404, 503 etc).

Imports System.Diagnostics
        Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
            
            Try
                Dim ErrorDescription As String = Server.GetLastError.ToString
                'Creation of event log if it does not exist  
                Dim EventLogName As String = "SibaException"
                If (Not EventLog.SourceExists(EventLogName)) Then
                    EventLog.CreateEventSource(EventLogName, EventLogName)
                End If
 
                ' Inserting into event log
                Dim Log As New EventLog()
                Log.Source = EventLogName
                Log.WriteEntry(ErrorDescription, EventLogEntryType.Error, [HERE IT WOULD B NICE TO SEND ERROR CODE AS INTEGER])
            Catch ex As Exception
            End Try
 
        End Sub
