[opencms-dev] Problem with storing session data in JDBCStore, but only on 7.0.4

[Yves Glodt]

Hallo Achim,

Thanks for the information!

Strangely, on my 7.0.5 installation, I can actually use the workplace while I 
have set <Manager distributable="true">, but it seems the session is not 
really ok, since after some time the workplace loses the information about 
which site I chose before.

So, in case I need to replicate the sessions between 2 tomcats, the best would 
be using the "in-memory"-replication as described here:
http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html ?

Best regards,
Yves
