ASP.NET站点之间共享认证 [英] Sharing Authentication between ASP.NET sites

问题描述

我有两个ASP.NET网站（他们不能在同一个进程中运行），我需要他们之间共享的认证。如果用户在站点A已经通过身份验证，然后进入到站点B，我需要有一种方法来与网站B股此信息，以便用户不会要求再次进行身份验证。也是同样的道理两种方式。你如何分享这些信息？

I have two ASP.NET sites (they can not run in the same process) and I need to share authentication between them. If a user is in site A already authenticated and then goes to site B, I need to have a way to share this information with site B so the user is not asked to authenticate again. The same is true both ways. How do you share this information?

推荐答案

他们是在同一个域中？

如果您有app1.blah.com和app2.blah.com，这是非常容易做到的。刚才设置的域名和名字在w​​eb.config中的窗体的部分相同的值：

If you have app1.blah.com and app2.blah.com, it's very easy to do. Just set the domain and the name to the same value in the forms-section in web.config:

<authentication mode="Forms">
      <forms loginUrl="login.aspx"
        name=".COOKIENAME" 
        protection="All"  
        path="/" 
        domain="blah.com" 
        timeout="30" />
    </authentication>

另外一个好处是，用户可以登录任一站点，并仍将进行身份验证，如果他们去另一个。

An added benefit is that users can sign into either site and will still be authenticated if they go to the other one.
