WL_Plugin Is Ignoring Server Session Info When Weblogic Cluster Have Remote Nodes (Doc ID 1958015.1)

Last updated on JANUARY 04, 2015

Applies to:

Oracle WebLogic Server - Version 10.3.6 to 12.1.3.0.0
Information in this document applies to any platform.

Symptoms

HTTP Sessions are being ignored and re-initialized the sessions frequently, so loosing session information.

By analyzing HTTP Headers from WLS for the first JSESSIONID
 
[Fri Nov 21 18:36:10 2014] [info] [client xx.xxx.xx.xxx]
weblogic: Header from  WLS:[Set-Cookie]=[JSESSIONID=MY4rJvvhwNJfvdjlJdYyJcx4q40QgkLv77dZGWbyFkKjTQNbTG1F; path=/; HttpOnly]
 
Here we can see that there is no host information set by WLS in the Set-Cookie filed. Normally after the alpha numeric numbers there will be a ! (exclamation mark) followed by a number used to be there eg: abcdefgh!12345678.
 
Hence from the next request which contains the request with JSESSIONID=MY4rJvvhwNJfvdjlJdYyJcx4q40QgkLv77dZGWbyFkKjTQNbTG1F; there is no way for plugin to parse the hostname in order to forward the request to the server where the session is set previously.
