Documentation Request Summary:

This change implements several new setParameters that can be used to adjust settings on the LogicalSessionCache on each server. These are described below:

logicalSessionRecordCacheSize - the maximum number of session records that the cache holds before it will begin evicting records. Defaults to 10,000.

logicalSessionRefreshMinutes - the interval after which the logical session record will refresh against the main session store. Defaults to 5 minutes.

localLogicalSessionTimeoutMinutes - TEST PARAMETER ONLY. We do not recommend that this be used in production. Sets the session timeout on this server only. This parameter must be set to the same value on every server in the cluster or sessions will not function properly. Defaults to 30 minutes.
