避免并发登录（注销前登录会话）在ASP.net成员资格 [英] Avoid concurrent login (logout former login session) in ASP.net membership

问题描述

我学习的ASP.net会员功能。

I am learning the ASP.net membership feature.

我想知道我怎么能实现如此注销前的登录会话，后来登录会话避免并发登录。我知道如何检查用户是否在线（通过Membership.IsOnline（）），并注销当前用户（由FormsAuthentication.SignOut（））。但我不知道该怎么注销previous登录会话。

I am wondering how I can implement so that later login session logout former login session to avoid concurrent login. I know how to check whether the user is online (by Membership.IsOnline()) and logout the current user (by FormsAuthentication.SignOut()). But I don't know how to logout the previous login session.

任意code或引用，我可以读？

Any code or reference that I can read?

推荐答案

我不认为有一个明确的方式来做到这一点。

I don't think there is an explicit way to do this.

要实现这将是存储在令牌缓存某种日志（会话ID？），当用户登录。每次吊销旧令牌用户登录，然后添加一个HttpModule哪些检查方法之一令牌......当收到请求时不匹配，注销用户。此外，把一个母版页这样的逻辑或页面对象从所有的应用页面继承。

One way to implement it would be to store some sort of log in token (session ID?) in the Cache when a user logs in. Revoke the old token each time that user logs in. Then add an HttpModule which checks this token... when a request comes in that does not match, log the user out. Alternatively, put this logic in a master page, or a page object from which all your app pages inherit.
