First of all, I'm sorry for the html in my previous mail: those of you that
receive the list in digest mode know what I mean...

I did some simple tests as suggested from Elfyn.
The test are copied below.

File -- ServerTransferTest.aspx

<%@ Page language="c#" AutoEventWireup="true" Inherits="System.Web.UI.Page"
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > 
<script runat="server">
	private void Page_Load(object sender, System.EventArgs e)
		{
			Server.Transfer("ServerTransferred.aspx");
		}
</script>
<html>
  <head>
    <title>ServerTransferTest</title>
  </head>
  <body>
    <form id="Form1" method="post" runat="server">
	Server TO TRANSFER!!!!
     </form>
  </body>
</html>

File -- ServerTransferred.aspx

<%@ Page language="c#" AutoEventWireup="false" Inherits="System.Web.UI.Page"
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > 
<html>
  <head>
    <title>ServerTransferred</title>
  </head>
  <body>	
    <form id="Form1" method="post" runat="server">
		Server transferred.
     </form>
  </body>
</html>

Loading from a browser the ServerTransferTest.aspx page causes the XSP to
crash without information. Note that there's no precompilation needed so
it's all "made in mono".

To have further information I activated the --verbose switch (mono
--profile --verbose C:\PROGRA~1\MONO-1~1.5\lib\mono\1.0\xsp.exe --root .
--port 8088 --applications /:. > prof1.txt). I report the rows involved in
the request below:

The last row tells that a NullReferenceException is thrown but not why.

I run mono 1.0.5 on WinXP.
Is there someone that have an idea of what is wrong?

Thanks,
