如何检测用户第一次访问我的网站并显示友好信息？

< %@ LANGUAGE="VBscript" % >
< %
RequestName = Request.Form("Name")
RequestLeaveMeAlone = Request.Form("LeaveMeAlone")
If RequestName < >"" or RequestLeaveMeAlone < >"" then

' 在同一个页面中检查表单变量.
Response.Cookies("MySiteVisitorName") = RequestName
Response.Cookies("MySiteVisitorName").Expires = #January 01, 2008#
Response.Cookies("MySiteLeaveMeAlone") = RequestLeaveMeAlone
Response.Cookies("MySiteLeaveMeAlone").Expires = #January 01, 2008#

' 如果表单变量存在,就创建Cookie,并设置到期时间.
End if

VisitorName = request.Cookies("MySiteVisitorName")
LeaveMeAlone = request.Cookies("MySiteLeaveMeAlone")

' 读取Cookie.

If VisitorName ="" and LeaveMeAlone ="" then

' 如果用户机子上不存在该Cookie,就创建一个表单询问相关信息.
