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<>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

' don't write to log file

If Left(Request.ServerVariables("HTTP_REFERER"), 17)

="http://jb51.net" Then

ValidEntry = False

End if

If Left(Request.ServerVariables("HTTP_REFERER"), 21)

="http://www.jb51.net" Then

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
