Configuring the Manager for Sessions Support
maxInactiveInterval
The maximum inactive interval (in minutes) for any sessions created. The default
value is 30 minutes.
The value of this property is automatically inherited from the web application
deployment descriptor (WEB-INF/web.xml) based on the value specified in the
<session-timeout> element.
NSJSP provides two implementations of the manager:
•
The default, NSJSPStandardManager, provides no persistence and stores
sessions in memory only.
•
The optional, NSJSPPersistentManager, stores active sessions that have been
swapped out and also saves sessions across restarts of the NSJSP container. By
configuring the appropriate <Store> element nested under the <Manager>
element, you can specify the storage location for the session data.
NSJSPStandardManager (Standard Implementation)
NSJSPStandardManager is the standard manager implementation that is used for
any context unless overridden by specifying a <Manager> element nested under a
<Context> element. This manager implementation does not provide session
persistence: sessions are stored in memory only.
In addition to the attributes specified in Configuring the Manager for Sessions Support
on page 3-51, NSJSPStandardManager supports the following attributes:
algorithm
Name of the message digest algorithm to calculate the session identifiers it
generates. The java.security.MessageDigest class must support this value.
The default value is MD5.
checkInterval
The number of seconds between checks for expired sessions. The default value
used is 60 seconds.
debug
The debug level for messages logged to the associated <Logger>. Higher
numbers generate more detailed output. The default is 0 (zero).
entropy
A string value used when seeding the random-number generator that creates
session identifiers. If this attribute is not specified, a preset value is used. For a
security-conscious environment, use a long string value.
