Rails CookieStore::CookieOverflow，不适合所有用户，仅在生产中
我有几个用户收到此 CookieStore::CookieOverflow 错误。
我对 nginx/passenger 表示怀疑，因为我上周刚刚切换到 nginx/passenger（从 nginx/thin），现在这些正在发生。
这始终是一个特定的操作，但并不是所有用户都会发生。我检查了会话中存储的内容，但没有保存任何大型对象，只保存了几个 id 和几个布尔值。
如果我在会话中存储大对象，我希望所有用户都会遇到此错误。
有关如何解决此问题的建议会很有帮助。
I have a couple users that are getting this CookieStore::CookieOverflow error.
I'm suspicious of nginx/passenger because I just switched to that last week (from nginx/thin) and now these are happening.
It's always a particular action, but it doesn't happen for all users. I checked to see what I'm storing in the session and I'm not saving any large objects, just a couple ids and a couple boolean values.
If I were storing big objects in the session, I'd expect all users to have this error.
Suggestions on how to troubleshoot this would be helpful.

跟踪和调试 CookieStore::CookieOverflow 错误并不简单。您应该尝试在网站上复制完全相同的用户活动。
修复该错误的一些建议：
* 切换到更具可扩展性的cookie存储，例如ActiveRecord或Memcached
* 尝试减少会话中存储的元素数量
另请注意，Flash 消息存储在会话中。如果您发回非常长的 Flash 消息文本，您可能会遇到 CookieOverflow 错误。
Tracking and debugging a CookieStore::CookieOverflow error it's not simple. You should try to replicate exactly the same user activity on the site.
A couple of suggestions to fix the error:
* switch to a more scalable cookie storage such as ActiveRecord or Memcached
* try to reduce the number of elements stored in session
Also note that flash messages are stored in session. If you send back a really long flash message text you might expect a CookieOverflow error.
会话中存储的三个日期对象导致了此问题。从会话中删除它们可以阻止错误的发生。
Three Date objects stored in the session were causing this. Removing them from the session stopped the error from happening.
