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)
