Closed as program error.
| Error description
This problem occurs only when there is a switch between the two
clones for a HttpSession.For example if clone1 receives the
first request creates a session object and after that all
subsequent requests to the second clone. Local fixProblem summary
r uses cache id to maintain the latest version of the session ob
ject in the cache. With URL Rewriting there might be scenarios
where a URL containing an obsolete session id might be sent over
from a browser. This normally should not matter once session aff
inity is established. However, in failover cases there might be
windows where the session manager may use the stale object inste
ad of going to the database leading to loss of session data. Problem conclusion
arguement called verifyDatabaseCopy has been introduced which wh
en set to true will cause the session manager to compare the las
t accessed time from the database with the in memory
copy and in case of a mismatch will cause the session object to
be read in from the database.It needs to be noted that this wil
l introduce some amount of performance degradation since each re
quest for a session object will execute an additional sql statem
t to the database. Temporary fixComments
