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。那是在更早的时候起作用的。不幸的是，我直到现在才注意到这一点，所以我不能说是什么导致了问题。但我认为这与通用提供商新版本 1.2(8 月 16 日发布(的更新有关。
我对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>
管理器一切正常(登录视图、带有站点地图修剪的菜单等(，但它只是不再缓存角色。会员提供程序、会话状态等也工作正常，并且它们的 cookie 设置正确。
静态角色类的所有属性都已正确设置，Httpcontext 中的所有内容(IsSecureConnection 等(也都是正确的。
角色 cookie 是较早设置的，但现在不再设置了。我希望任何人都可以帮助我解决我的问题。
提前谢谢。

更新：请问没有人遇到同样的问题或给我提示吗？
下面是我编写的自定义角色提供程序的详细信息，它使用正确的缓存，并且不会在每次页面加载时命中数据库。

干杯。
我遇到了同样的问题，但我能够找到一篇似乎已经修复它的 MS KB 文章。我安装了补丁，饼干再次出现。
