Chrome/Firefox lost some cookie

[huakaibird]

Hi,

I have one strange issue:

I use nginx 1.8.0 on CentOS 7.1, found that some cookie will lost on
chrome/firefox, but IE works, and one of my nginx works
these nginx's configurations are same 

This is cookie copy from chrome, it lost _zm_sid cookie, response has the
cookie  (which is secure and http only)
