How to get HttpResponse size

I am looking for a way to get the number of bytes sent to a specific point in an ASP.NET 2.0 response so that I can write that number in the response. Sort of:

Page.aspx:

<script runat="server">
    private string GetResponseSize()
    {
        int nCurrentResponseSize = ...; // what goes here?
        return ( nCurrentResponseSize.ToString() );
    }
</script>
<html>
  <head runat="server"><title>test</title></head>
  <body>
    <div>Size 1: <%= GetResponseSize() %></div>
    <br />
    <div>Size 2: <%= GetResponseSize() %></div>
  </body>
</html>

The problem is that it is HttpResponse.OutputStream.Lengthnot supported ( NetworkStream does not support it).

I could implement HtmlTextWriterto override the default value and count bytes, but something inside ASP.NET should already have a counter and I'm trying to figure out if this is possible.

What I would like to avoid are solutions that include getting all the data and then parsing it to a specific point to find the size to that point. Until now, only such solutions have appeared in most of my searches.

dotPeek, , HttpResponse GetBufferedLength, :

int bufferedLength1 = httpContext.Response.GetBufferedLength();
this.RenderControlInternal(writer, adapter);
int bufferedLength2 = httpContext.Response.GetBufferedLength();
