Subject [jira] Commented: (GERONIMO-2677) HttpSession Relocation - Sticky load-balancing via HTTP Cookie
Date Mon, 01 Jan 2007 10:32:27 GMT

    [ http://issues.apache.org/jira/browse/GERONIMO-2677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12461613
] 

Gianny Damour commented on GERONIMO-2677:
-----------------------------------------

I attach two patches:

* JETTY-2677.patch: Jetty6 patch in order to simplify the integration code.

** AbstractSessionManager.Session is updated such that its two constructors share the same
logic with respect to the definition of the _id field. Also, the method initValues is added
such that sub-classes can explicitly control the initialization of the _values field.
** SessionHandler.handle is refactored: the method setRequestedId has been extracted such
that sub-classes can also share this behavior; and
** Request.getSession(boolean) is improved such that a session cookie is set against a session
whose id has changed (following a migration).

* GERONIMO-2677.patch: Geronimo patch to leverage the Jetty6 code base after having applied
the Jetty6 patch.

> When an HttpSession is migrated from one node to another:
> * its id must be updated (the worker name suffix is to be set to the name of the node
owning the HttpSession); and
> * the session cookie must be updated accordingly.
> The worker name suffix, which can be retrieved from the session cookie, can be leverage
to configure sticky load-balancing.
