一个网站的来访量，我们是怎么知道的呢？这里就不的不说到用Asp创建日志文件的知识了。这个原理其实是使用文本文件来写入用户的信息，比如说创建一个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。想知道具体的代码？呵呵，不用着急，且看创新互联网站建设小编意义道来。
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://jzxue.com Then
ValidEntry = False
End if
If Left(Request.ServerVariables("HTTP_REFERER"), 21)
=http://www.jzxue.com 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
%>
