Multiple Tomcat Instances behind HTTPD - Session Expired

Jordan Fryar
6 years ago Sep 12, 2016 9:40pm

Environment:
     RHEL 6
     Apache HTTPD 2.2
     Tomcat 8
     Vaadin 7.6

Currently setup with multiple Tomcat instances, each on their own port, being proxied to via HTTPD (depending on the URL):
     Tomcat 1 hosts APP_1 on ajp port 8009
     Tomcat 2 hosts APP_2 on ajp port 8010

     myserver.com/APP_1/ is proxied to ajp://localhost:8009
     myserver.com/APP_2/ is proxied to ajp://localhost:8010

Each work just fine independently, however, the following error is encountered:
     1. APP_1 is opened in one tab of the web browser; navigated through for a few clicks
     2. APP_2 is opened in another tab; navigated through for a few clicks
     3. Reverting back to APP_1 yeilds a "Session Expired"

It looks to be an issue with cookies. The JSESSIONID is being changed after using APP_2, and it attempts to connect back to APP_1 using the new JSESSIONID. It seems to be a well-documented issue, but I have been unable to find any resolution. Any ideas?

Thanks in advance!
