ASP.NET通用提供商 - Roleprovider不缓存中的cookie的作用(ASP.NET

讽刺的是我的角色提供不缓存在cookie中的角色了。这是较早的工作。不幸的是我已经注意到了，只是现在，所以我不能说是什么原因导致的问题。但我认为它具有与更新到通用供应商的1.2（16日8月发布）的新版本做。

我对roleprovider配置是这样的：

 <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>

一切工作正常与rolemanager（loginviews，与sitemaptrimming等菜单），但它只是不再缓存的角色。成员资格提供程序，SessionState会等也正常，并且它们的饼干是否设置正确。

静态角色类的所有属性都设置正确，一切都在HttpContext的（IsSecureConnection等）也是正确的。

角色Cookie先前设置，但现在不是了。我希望有人能帮助我与我的问题。

提前致谢。

最好的祝福，

更新：有没有人有同样的问题，或者我一个提示吗？

下面是自定义角色提供我写了一个使用适当的缓存和不打在每个页面加载数据库的细节。

高速缓存设置为每隔30分钟后自动失效。你认为合适，您可以对此进行修改。

干杯。

我有同样的问题，但我能找到似乎已经解决了它的MS知识库文章。我安装了补丁和饼干又出现了。
