ASP.NET会话状态在异常后丢失

这本身就很奇怪,因为请求上下文中的异常不会影响工作进程.它可能是后台线程或回调或其他东西的例外,但这是一个简单的网站,没有任何花哨的东西.

会话ID保持不变,并且后续请求不会调用Session_Start(因此WP未回收).

我已经启用了很多日志记录,并且可以看到我从数据层获得异常,它在HttpUnhandleException内部是一个HttpException,然后当我立即浏览到主页时,请求会记录关于缺失的警告州.

更差.这不会发生在我的开发箱(IIS Express)上,仅在QA中.

这是一大块日志：

最后一行显示缺少的状态条件. pxtgn是会话ID中的前5个字符.我点击了一个页面,我知道数据层将关于不存在的图像ID.然后我点击的任何页面将导致我的检查记录缺失状态的问题.检查和状态引用位于母版页的代码中,因此我可以点击任何页面来查看问题.这也意味着自定义错误页面不起作用 – 这就是我找到错误的方式.

我现在在检查后添加了一个Session.Abandon()并用500回应让我离开监狱,但这是一个非常奇怪的问题.我是代码库的新手,我想我已经在所有地方检查了被清除的会话或被覆盖的状态.
