用ASP创建日志文件（附源程序）

　　这个例子使用文本文件来写入用户的信息创建一个logfile.asp放在每一个asp的页面的顶端<!--#Include File=LogFile.asp-->当有人来访问你的站点logfile.asp自动把他的信息写入LogFile.txt,如果相关的URl一样的话则不写入文件
File: LogFile.asp
复制代码 代码如下:
<%
Dim ValidEntry Log variable
First set that this log is valid
ValidEntry = True

If Session Variable LogIn is not empty
that mean this person has already been logged
then set ValidLog to False
If not IsEmpty(Session(LogIn)) then ValidEntry = False

Here you can add different restriction
If the refering url is from same site
dont write to log file
If Left(Request.ServerVariables(HTTP_REFERER), 17)
=
ValidEntry = False
End if
If Left(Request.ServerVariables(HTTP_REFERER), 21)
=//
ValidEntry = False
End If

Now if ValidEntry is True then enter to log file
If ValidEntry Then
Const ForAppending = 8
Const Create = true
Dim FSO
DIM TS
DIM MyFileName
Dim strLog

MyFileName = Server.MapPath(MyLogFile.txt)
Set FSO = Server.CreateObject(Scripting.FileSystemObject)
Set TS = FSO.OpenTextFile(MyFileName, ForAppending, Create)

Store all required values in strLog
strLog = <br><P><B> & now & </B>
strLog = strLog & Request.ServerVariables(REMOTE_ADDR) &
strLog = strLog & Request.ServerVariables(HTTP_REFERER) &
strLog = strLog & Request.ServerVariables(HTTP_USER_AGENT) & <BR>
Write current information to Log Text File.
TS.write strLog
TS.Writeline
Create a session varialbe to check next time for ValidEntry
Session(LogIn) = yes
Set TS = Nothing
Set FSO = Nothing
End If
