-----------------------------------
Summary: Add section with more details about sticky vs non-sticky
sessions for Tomcat Session Module
Key: GEODE-6872
URL: https://issues.apache.org/jira/browse/GEODE-6872
Project: Geode
Issue Type: Bug
Components: docs
Reporter: Ryan McMahon
Sticky vs non-sticky sessions and the recommended configurations should be
discussed in better detail the docs (it is not discussed at all for Tomcat
module). If the user configured client-server topology with non-sticky
sessions, we do NOT recommend enableLocalCaching be set because it results in
unpredictable asynchronous behavior/replication.
If they follow our recommendations and disable local caching (proxy-only
client), then they should also set `gemfire.EXPIRE_SENDS_ENTRY_AS_CALLBACK`.
Otherwise the expire logic will not be called on the client. The side effects
of this may be benign, but if there are any listeners depending on that
expiration logic, it may result in bugs or a resource leak.
