+ 22 March - JK-1.2.28 released
+ The Apache Tomcat team is proud to announce the immediate
+ availability of Tomcat Connectors 1.2.28. This is a stable release
+ concentrating mainly on some bug fixes.
+
+ Please see the ChangeLog for a full list of changes.
+
+ If you find any bugs while using this release, please fill in the
+ Bugzilla Bug Report.
+
+ The most important new features in this version are:
+
+ Better Error Detection for Load Balancer Workers
+
+ Local and global error states have been improved. You can fine tune
+ the behaviour with the new "error_escalation_time" attribute (see the
+ timeouts documentation).
+
+ Dynamic Address and Port Change Using the Status Worker
+
+ The status worker now allows you to change the address and the port
+ of an AJP13 worker on the fly. You can e.g. provision dummy workers
+ with a port equal to "0", which will be automatically put into
+ stopped mode during startup. Later, when you want to actually use
+ thse workers, you set their address and port to the final values.
+
+ Note that already existing connections will go on using the old
+ address and port. This will be improved in future versions.
+
+ New Data in Status Worker Display
+
+ The status worker display now also contains the timestamp of the last
+ worker errors.
+
+ Improved Proxy Flexibility
+
+ You can now overwrite more request metadata before the request gets
+ send to the backend. This is helpful in case there are other reverse
+ proxies in front of your web server. A new documentation page
+ explains this in detail.
+
+ Improved IIS Support
+
+ IIS support has been improved especially when using mutltiple
+ application pools. Furthermore you can now configure the ISAPI plugin
+ to update the uriworkermap.properies file on a regular interval using
+ the watchdog thread.
+
+ JNI Worker Deprecation
+
+ Workers of type jni are broken since a long time. Since there is no
+ more use for them, they have been deprecated now, and will be removed
+ in a future release.

+
+ 2008 News & Status
+ 28 October - JK-1.2.27 released
+ The Apache Tomcat team is proud to announce the immediate
+ availability of Tomcat Connectors 1.2.27. This is a stable release
+ adding lots of new features and some bug fixes.
+
+ Please see the ChangeLog for a full list of changes.
+
+ If you find any bugs while using this release, please fill in the
+ Bugzilla Bug Report.
+
+ The most important new features in this version are:
+
+ Watchdog Thread for Periodic Tasks
+
+ The connector has to run some periodic tasks independant of request
+ processing. Examples are probing or closing down idle backend
+ connections, adjusting load numbers and recovering workers from error
+ state.
+
+ Before version 1.2.27 these tasks were done inside the request
+ processing loop. When a new request came in and the task was due, the
+ thread handling the request first executed the internal task and then
+ handled the request. If there were no requests coming in, the tasks
+ would not run. If any of the tasks took unexpectedly long, the
+ response time of the request waiting for the finishing of the task
+ went up.
+
+ Starting with this release you can configure a separate watchdog
+ thread inside the web server to run all those tasks independantly of
+ request processing. This new feature is avaliable for the connector
+ when used with Apache httpd 2.x or with Microsoft IIS. To keep the
+ behaviour of the new version consistent with previous releases, this
+ feature is turned off by default. You can activate the watchdog
+ thread via JkWatchdogInterval for Apache or watchdog_interval for
+ IIS.
+
+ Connection Probing
+
+ In previous releases connection probing (checking whether connections
+ still work) could only be done immediately after a new connection was
+ established and directly before sending each request. Since we now
+ have the watchdog thread available, we also added a periodic probing
+ option, which you can activate with the worker attribute ping_mode.
+ This will also be useful as a protection against the infamous
+ firewall idle connection drop.
+
+ The older attributes connect_timeout and prepost_timeout still exist
+ and work the same way they did in previous releases. Since there are
+ now three different probing options, we recommend to migrate your
+ configuration to the newer attributes ping_mode, ping_timeout and
+ connection_ping_interval.
+
+ Mount Extensions
+
+ Usually one defines workers and mounts for the connector. A worker
+ defines a backend we want to talk to and the configuration parameters
+ of the communication, connection pools etc. The mounts define which
+ URIs we want to forward to which worker (so we also call a mount an
+ URI map rule). In version 1.2.27 you can overwrite certain worker
+ parameter per mount.
+
+ One easy to understand example is reply timeouts. Until this release
+ you had to specify a reply timeout for the whole worker. But reply
+ times depend a lot on the type of request. So normally you want to
+ define a general reply timeout and for some special URLs you need to
+ relax the reply timeout, because you know those URLs take much longer
+ to process (like e.g. reporting or other compute intensive tasks).
+
+ Another possible case is the activation status. You might use a load
+ balancer worker to forward requests to certain webapps in a farm of
+ Tomcat nodes. If you wanted to update some webapp on one node, you
+ previously had to stop forwarding requests for all webapps on this
+ Tomcat node. What was not possible until now, was stopping forwarding
+ requests restricted to the webapp and the node you wanted to update.
+
+ Starting with this release, you can add so-called rule extensions to
+ your uriworkermap file to influence worker parameters per mount. This
+ will work for all Apache versions and for IIS. Remember, that the
+ uriworkermap file automatically gets reloaded after changes without
+ web server restart.
+
+ Improved IIS support
+
+ We improved IIS support im various ways. It is now possible to use
+ multiple IIS 6 application pools with the ISAPI redirector.
+
+ Furthermore some improvements were added as compile time features.
+ The most notable one is chunked encoding support, which was a major
+ refactoring and is therefore still considered experimental. You can
+ download binaries with and without chunked encoding support. In
+ future versions, chunked encoding will likely be availabe in all
+ builds.
+
+ Another new feature is an elegant way of configuring error page
+ redirects. All new features are documented on the documentation page
+ about configuring IIS.
+
+ Enhanced Status Worker
+
+ The status worker now can also manage and show statistics for AJP
+ workers that are not part of a load balancer. Other improvements are
+ the new dump action, the integration of the new configuration
+ attributes, showing average request and transfer rates since the last
+ statistics reset and the ability to display only a single member of a
+ load balancer.
+
+ Unfortunately we had to change some request parameters used for the
+ update action of the status worker.
+
+ Miscellaneous Improvements
+
+ Further enhancements are:
+
+ * Configurable session stickyness indicator: cookie name and URL
+ path parameter name can be freely chosen instead of the servlet
+ spec compliant JSESSIONID and ;jsessionid.
+ * Automatically determining the size of the shared memory segment
+ needed to accommodate all workers.
+ * New connection establishment timeout socket_connect_timeout.
+ * New timeout connection_acquire_timeout for acquiring a free
+ connection from the pool.
+ * Improved retry handling by adjusting the meaning of the attribute
+ retries for AJP workers and for load balancers and by adding the
+ new retry_interval.
+ * Allowing the web server to provide error pages instead of Tomcat.

+
+ 15 November - JK2 is officially unsupported
+
+ JK2 has been put in maintainer mode and no further development will
+ take place. The reason for shutting down JK2 development was the lack
+ of developers interest. Other reason was lack of users interest in
+ adopting JK2, caused by configuration complexity when compared to JK.
+
+ The latest official JK2 release is 2.0.4.
+
+ JK2 will have it's successor within core Apache2.1/2.2 distribution. We
+ have developed new proxy_ajp that is an addition to the mod_proxy and
+ uses Tomcat's AJP protocol stack. It is developped in httpd-2.1 and
+ integrated in it. We have also developed a new proxy_balancer module
+ for load balancing http and ajp protocol stacks.
+
+ JK will be fully supported for all other web servers. The next JK
+ release is planned for the end of November. Lots of code from JK2 has
+ been ported to JK
