If you are familiar with Asp you could a scripting object (TextStream object) to create a log file.
Use this code as a server side include file
<%
Const ForAppending = 8
Dim strLogFileName
strLogFileName = "c:\....." 'your path here
dim objlogFile
set objlogFile = createObject("Scripting.FileSystemObject"
Dim objLogFileTS
If objLogFile.FileExists(strLogName) Then
Set oblLogFileTS = objLogFileFSO.OpenTextFile(strLogFileName, ForAppending)
Else
Set objLogFileTS = objLogFileFSO.CreateTextFile(strLogFileName)
End if
'the following subroutine will write the information into your log file
sub WriteToLog(strNewEntry)
Dim strLogEntry
strLogEntry = formatDateTime(now) & "-"
strLogEntry = strLogEntry & strNewEntry
objLogFiltTS.WriteLine strLogEntry
End Sub
Sub CloseLog()
objLogFileTS.Close
end Sub
