Men det fina men ASP.NET är ju att du inte är bunden till ett språk.
Du kan ju använda det C#-exempel som finns här på wF även om dina andra sidor är i VB.

Ok, men hur funkar det då, ska jag kompilera C# exemplet till en egen dll och importera den eller, och hur i så fall?

För övrigt så konverterade jag C# exemplet till VB genom en konverterare. Denna kod har jag sedan lagt i global.asax och det funkar bra, förutom att jag måste avmarkera *Buffer.BlockCopy(buffer, offset, data, 0, count)* eftersom detta ej verkar vara tillgängligt i VB?

Här är VB klassen

```
Public Class XHTMLStrictFilter
    Inherits Stream
    Private _sink As Stream
    Private _position As Long

    Private Shared _regForm As New Regex("<form .*name=.* .*>", RegexOptions.Compiled Or RegexOptions.IgnoreCase)
    Private Shared _regNameReplace As New Regex("name=[^ ]*", RegexOptions.Compiled Or RegexOptions.IgnoreCase)
    Private Shared _regViewState As New Regex("<input type=""hidden"" name=""__VIEWSTATE"" value="".*"" />", RegexOptions.Compiled Or RegexOptions.IgnoreCase)

    Private _formFix As Boolean
    Private _viewStateFix As Boolean

    Public Sub New(ByVal sink As Stream)
        _sink = sink
    End Sub 'New

    ' The following members of Stream must be overriden.

        Get
            Return 0
        End Get

        Get
            Return _position
        End Get

            _position = Value
        End Set
    End Property

    Public Overrides Function Seek(ByVal offset As Long, ByVal direction As System.IO.SeekOrigin) As Long
        Return _sink.Seek(offset, direction)
    End Function 'Seek

    Public Overrides Sub SetLength(ByVal length As Long)

    ' The Write method actually does the filtering.

        Dim data() As Byte

        If Not _formFix Or Not _viewStateFix Then
            Dim htmlOutput As String = System.Text.UTF8Encoding.UTF8.GetString(buffer)
            Dim length As Integer = htmlOutput.Length
            If Not _formFix And _regForm.IsMatch(htmlOutput) Then
                Dim formMatch As String = _regForm.Match(htmlOutput).Value
                htmlOutput = Regex.Replace(htmlOutput, formMatch, _regNameReplace.Replace(formMatch, ""), RegexOptions.IgnoreCase)
                _formFix = True

            End If
            data = System.Text.UTF8Encoding.UTF8.GetBytes(htmlOutput)

        Else
            data = New Byte(count) {}
            'Buffer.BlockCopy(buffer, offset, data, 0, count)
        End If
        _sink.Write(data, 0, count)
