Asp. NET form Forms authentication invalidation problem solving method in Ie9,ie10,ie11

Solutions have been developed.

IE9:
Add the Name= ". Xcookie" attribute to forms in Web. config.

IE10 or IE11:

Add the cookieless= "UseCookies" attribute to forms in Web. config.

这个是IE9，IE10，和IE11浏览器的bug问题,相信很多用FormsAuthenticationTicket来做验证的都会碰到这个问题。。。。。

我自己的最后的是

<authentication mode="Forms"><forms name=". Xcookie" loginurl= "login.aspx" protection="all"  timeout= "cookieless="usecookies"/>< /authentication>
