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。那是在早些时候工作。不幸的是，我注意到只有现在，所以我不能说是什么导致了这个问题。但我认为这与通用提供商的新版本1.2（8月16日发布）的更新有关。

我对roleprovider的配置如下：

 <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（loginviews，带有sitemaptrimming等的菜单）一切正常，但它不再缓存角色了。会员提供者，会话状态等也正常工作，并且正确设置了它们的cookie。

静态Roles类的所有属性都已正确设置，Httpcontext（IsSecureConnection等）中的所有属性也都正确。

角色Cookie是先前设置的，但不再是。我希望有人可以帮我解决我的问题。

提前致谢。

最诚挚的问候，

更新请问有没有人遇到同样的问题或提示？

以下是我编写的自定义角色提供程序的详细信息，该提供程序使用正确的缓存，并且在每次加载页面时都没有访问数据库。

缓存设置为每30分钟后自动过期。你可以根据自己的意愿修改它。

干杯。

我遇到了同样的问题，但我找到了一篇似乎已修复它的MS KB文章。我安装了补丁并重新出现了cookie。
