Why are there multiple session IDs logged in the TIBCO Spotfire client logs for the same user session?

Product:TIBCO Spotfire Server
Versions:All

Summary:
This article explains why there could be multiple session IDs in the Spotfire client logs.

Details:
When looking in the Spotfire client logs, you may sometimes see multiple session IDs for the same user session. 

Here is an example of a session ID getting generated. This example is taken from the Web Player logs.

DEBUG 2021-07-08T17:49:24,708+0000 [unknown, #64, #287041] server.security.SessionUtil: Generated a new 'internal session id': 061671aee09ad4b59cc22532d3a64ecd

Resolution:
Here are the most common causes of this behavior:

• The Spotfire client has a load balancer in front of the Spotfire Server that does not route the requests to the same Spotfire Server throughout the session.
• After an inactivity timeout, when the user has logged in again.
