ASP調用純真IP庫實例(2)_ASP教程

推薦：ASP實例：ASP實現空間的最近訪客
由于工作關系，在做一個用戶空間。要用到空間的最近訪客，見ASP代碼： % username=request.QueryString(username) '地欄中的username,就是自己的用戶名了 if trim(request.Cookies(user_name)) Then '首頁要判斷該訪問是否登陸，只有登陸的訪問才能記

分享：ASP防止GET,Post注入和防止服務器攻擊,并記錄IP
% '防止GET,Post注入和防止服務器攻擊 '使用方法把本文件包含到需要防注的文件就OK了,說明下,這里的post攻擊和Get攻擊不一定是攻擊,在英文版本的時候請注意使用 '馮旭修改 session.Abandon() Dim fxjt111_Attack_post,fxjt111_Attack_Get,fxjt111_Attack_Sys
