用户访问重定向技术的研究

Study on User Access Redirection Technology

分析基于HTTP和PPPOE(PADM)的两种重定向技术原理和应用场景范围、实现难度约束等,综合权衡给出基于HTTP的通用重定向技术应用建议。通过在用户网关部署该项技术,实现用户的认证前强制Portal、认证后的强推Portal,进行认证服务器地址推送、广告业务推广以及认证计费失败信息展示、强制终端安全检测检查和杀毒引导等增值业务推送。创造性地将HTTP重定向技术结合用户接入认证、广告推动、终端安全检查等业务场景进行关联,实现独特的重定向技术应用价值,包括基于用户位置/账号等属性的个性化Portal业务等。

This paper analyzes the principles of two redirection technologies based on HTTP and PPPoE(Padm),the scope of application scenarios,the constraints of implementation difficulty,etc.,and gives the application suggestions of general redirection technology based on HTTP.Through the deployment of this technology in the user gateway,it realizes the forced portal before and after the user’s authentication,pushes the address of the authentication server,promotes the advertising business,displays the failed information of authentication and billing,forces the terminal security inspection and anti-virus guidance and other value-added business push.Creatively associate HTTP redirection technology with user access authentication,advertising promotion,terminal security check and other business scenarios to realize unique application value of redirection technology,including personalized portal business based on user location/account and other attributes.
