如何檢測用戶第一次訪問我的網(wǎng)站并顯示友好信息？

    < %@ LANGUAGE="VBscript" % >
    < %
    RequestName = Request.Form("Name")
    RequestLeaveMeAlone = Request.Form("LeaveMeAlone")
    If RequestName < >"" or RequestLeaveMeAlone < >"" then
    ' 在同一個(gè)頁面中檢查表單變量.
    Response.Cookies("MySiteVisitorName") = RequestName
    Response.Cookies("MySiteVisitorName").Expires = #January 01, 2008#
    Response.Cookies("MySiteLeaveMeAlone") = RequestLeaveMeAlone
    Response.Cookies("MySiteLeaveMeAlone").Expires = #January 01, 2008#
    ' 如果表單變量存在,就創(chuàng)建Cookie,并設(shè)置到期時(shí)間.
    End if
    VisitorName = request.Cookies("MySiteVisitorName")
    LeaveMeAlone = request.Cookies("MySiteLeaveMeAlone")
    ' 讀取Cookie.
    If VisitorName ="" and LeaveMeAlone ="" then
    ' 如果用戶機(jī)子上不存在該Cookie,就創(chuàng)建一個(gè)表單詢問相關(guān)信息.
