       The Apache Tomcat Connector - Miscellaneous Documentation

   Changelog

   Preface
     This is the Changelog for Tomcat Connectors. This changelog does not
     contain all updates and fixes to the Tomcat connectors (yet). It should
     contain fixes made only after November 10th 2004, when the new
     documentation project for JK was started.

   Changes between 1.2.20 and 1.2.21
     Native

           not a valid one. (jfclere)
       add 41439: Allow session IDs to get stripped off URLs of static
           content in Apache by adding JkStripSession directive
           (configurable per vhost). (mturk)
       add Change semantics of empty defaults for JkEnvVar variables. Until
           1.2.19: not allowed. In 1.2.20: send variables as empty strings,
           if neither set to non empty in config, nor during runtime.
           Starting with 1.2.21: If config has no second argument only send
           variable if set (even when set to empty string) during runtime.

   Changes between 1.2.6 and 1.2.7
     Native
       update Added new property named recover_time that can be used to
              change the default 60 second recover time. (mturk)
       update Added custom retries for worker, so we don't depend on default
              setting. If set to a number grater then 3, it will sleep for
              100ms on retry greater then 3 and then try again. (mturk)
       update Added JkWorkerProperty directive that enables omiting
              workers.properties file. For example: JkWorkerProperty
              worker.ajp13a.port=8009. (mturk)
       fix    Check all JSESSIONID cookies for a valid jvmRoute. If you have
              multiple Tomcats with overlapping domains, then you can get
              multiple cookies without a defined order. This will route
              correctly as long as the different domains don't have any
              Tomcats in common. (billbarker)
       update Added JkUnMount directive for negative mappings that works as
              opposite to JkMount directives. It is used for blocking of
              particular URL or content type. (mturk)
       update Added wildchar match uri mappings. One can now use JkMount to
              map /app/*/servlet/* or /app?/*/*.jsp. (mturk)
       update Rewrite the logging by adding Trace options. (mturk)
       update Added socket_timeout property that sets the timeout for the
              socket itself. (mturk)
       fix    Changed socket_timeout property to recycle_timeout. This
              better explains what the directive actually does. (mturk)
       fix    Changed the load balancer algorithm. The idea behind this new
              scheduler is the following: lbfactor is how much we expect
              this worker to work, or the worker's work quota. lbstatus is
              how urgent this worker has to work to fulfill its quota of
              work. We distribute each worker's work quota to the worker,
              and then look which of them needs to work most urgently
              (biggest lbstatus). This worker is then selected for work, and
              its lbstatus reduced by the total work quota we distributed to
              all workers. Thus the sum of all lbstatus does not change.(*)
              If some workers are disabled, the others will still be
              scheduled correctly. (mturk)

   JK 2
     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.
