Hi,
We are developing a web application wich uses session listeners and
such kind
of stuff in order to control which users are loged in every time.
Nevertheless we have experienced a developement problem due to the
session ID
changes when one node goes down.
30/07/2010 13:08:27 org.apache.catalina.ha.session.JvmRouteBinderValve
changeSessionID
FINE: Changed session from
[18434EBFCF3D1009BBEEE5C02D370BCF.workerW37] to
[18434EBFCF3D1009BBEEE5C02D370BCF.workerW38]
The jvmRoute part of the session ID is required for sticky sessions to
work. If a node goes down, the session fails over to another node and
hence the jvmRoute has to change.
I think session ID should not change its ID or should be a way to
avoid this
rename processs.
Is there any workarround or change this behaviour ?
1. Don't code your application assuming the session ID is constant
2. Don't use sticky sessions
3. Add a listener to handle the change in session ID
4. Remove everything behind a dot "." from the session id before using
it as a key into your own data.

Rainer
