ASP.NET通用提供程序- Roleprovider不缓存cookie中的角色

Question

具有讽刺意味的是，我的角色提供程序不再将角色缓存在cookie中。刚才起作用了。不幸的是，我现在才注意到这一点，所以我不能说是什么原因造成了这个问题。但我认为这与更新新版本1.2版的通用供应商有关(8月16日发布)。

角色提供程序的配置如下所示：

 <roleManager enabled="true" cacheRolesInCookie="true" cookieName="X_Roles" 
cookiePath="/" cookieProtection="All" cookieRequireSSL="true" cookieSlidingExpiration="true" cookieTimeout="1440" 
createPersistentCookie="false" domain="" maxCachedResults="25" defaultProvider="XManager_RoleProvider">
<providers>
<clear/>
<add name="XManager_RoleProvider" type="ManagersX.XManager_RoleProvider, AssemblyX" 
connectionStringName="XEntities" applicationName="/" rolesTableName="Roles" roleMembershipsTableName="Users_Roles"/>
</providers>
</roleManager>

使用rolemanager (loginview、菜单和站点地图修剪等)一切都很好，但它只是不再缓存角色了。成员资格提供程序、会话状态等也运行良好，并且正确设置了它们的cookie。

静态角色类的所有属性都被正确设置，并且Httpcontext (IsSecureConnection等)中的所有内容都是正确设置的。也是正确的。

角色cookie是早些时候设置的，但现在不是了。我希望有人能帮我解决我的问题。

提前谢谢。

诚挚的问候,

更新：没有人有同样的问题或提示给我，好吗？

下面是我编写的自定义角色提供程序的详细信息，它使用适当的缓存，并且不会在每次加载页面时命中数据库。

缓存设置为每隔30分钟自动过期。你可以在你认为合适的时候修改这个。

我也有同样的问题，但我找到了一篇MS的文章，似乎已经解决了它。我安装了补丁，饼干就重新出现了。
