tengine-1.5.2 after configuration Session_sticky does not return session cookie problem resolution

The problem arose when a Tomcat node was added to the back-end cluster of the company Tengine (1.5.2 version) yesterday, and session_sticky instructions were added to the load Balancer cluster to enable client session retention. When the client accesses the reverse proxy, it does not return a session cookie, which causes the SessionID to be refreshed each time the connection is requested and cannot be logged on. On this issue many times, review Tengine official email list, try a variety of configurations, tossing the day did not find a solution, only in the official provision of 1.5.0 version changelog See the fix that has been done on this issue:

Tengine-1.5.0 [2013-07-31]

• Bugfix: Fixed issue where session cookie was not issued by Session_sticky module in some cases [dinic]

The curl result does not return a session cookie (the cookie name configured here is called ROUTERC)

Under the 2.1.0 version:
