+ 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

+

+Bugzilla
+Bug Report.
+
+The most important new features in this version are:
+
+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
+
+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
+
+The older attributes
+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.
+
+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.
+
+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
+Unfortunately we had to change
+some request parameters
+used for the
+Further enhancements are:

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: +
++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). +
++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. +
++The status worker display now also contains the timestamp of the last +worker errors. +
++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. +
++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. +
++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. +
