Problem Statement:
A web-based application running in an Application Server (AS) 10.1.3.x instance reports 'session recovery' errors in the HTTP Server error_log even though no error is apparent to the end user, for example:
The application runs correctly and no functional errors are observed, but the error message appears very frequently in the HTTP_Sever error_log log file, leading to administration concerns.
This problem has been confirmed in an architecture consisting of a load balancer located in front of two Oracle AS 10.1.3.4 instances which are not clustered or jointly participating in session replication.
Steps to reproduce the errors:
1.- Access the web application as a guest to get access to the 'public zone'.
2.- Log in with with username/password to get into the 'private zone'.
3.- Log out from the 'private zone'.
4.- Navigate normally again in the 'public zone'.
After the step 4, the error begins to get logged to the HTTP Server error_log file.
