This is a stable release adding lots of new features -and some bug fixes. -</p><p> - Please see the <a href="../miscellaneous/changelog.html">ChangeLog</a> for a full list of changes. -</p> -<p>If you find any bugs while using this release, please fill in the -<a href="https://issues.apache.org/bugzilla/enter_bug.cgi?product=Tomcat%20Connectors">Bugzilla</a> -Bug Report. -</p> -<p> -The most important new features in this version are: -</p> -<h3>Watchdog Thread for Periodic Tasks</h3> -<p> -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. -</p> -<p> -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. -</p> -<p> -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 -<a href="../reference/apache.html"><code>JkWatchdogInterval</code></a> -for Apache or -<a href="../reference/iis.html"><code>watchdog_interval</code></a> -for IIS. -</p> -<h3>Connection Probing</h3> -<p> -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 -<a href="../reference/workers.html"><code>ping_mode</code></a>. -This will also be useful as a protection against the infamous firewall -idle connection drop. -</p> -<p> -The older attributes <code>connect_timeout</code> and <code>prepost_timeout</code> -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 <code>ping_mode</code>, -<code>ping_timeout</code> and <code>connection_ping_interval</code>. -</p> -<h3>Mount Extensions</h3> -<p> -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. -</p> -<p> -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). -</p> -<p> -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. -</p> -<p> -Starting with this release, you can add so-called -<a href="../reference/uriworkermap.html#Rule extensions">rule extensions</a> -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. -</p> -<h3>Improved IIS support</h3> -<p> -We improved IIS support im various ways. It is now possible to use -multiple IIS 6 application pools with the ISAPI redirector. -</p> -<p> -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. -</p> -<p> -Another new feature is an elegant way of configuring error page redirects. -All new features are documented on the documentation page about -<a href="../reference/iis.html">configuring IIS</a>. -</p> -<h3>Enhanced Status Worker</h3> -<p> -The -<a href="../reference/status.html">status worker</a> -now can also manage and show statistics for AJP workers that -are not part of a load balancer. Other improvements are the new <code>dump</code> -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. -</p> -<p> -Unfortunately we had to change -<a href="../reference/status.html#Data Parameters for the standard Update Action">some request parameters</a> -used for the <code>update</code> action of the status worker. -</p> -<h3>Miscellaneous Improvements</h3> -<p> -Further enhancements are: -<ul> -<li> -Configurable session stickyness indicator: cookie name and URL path -parameter name can be freely chosen instead of the servlet spec compliant -<code>JSESSIONID</code> and <code>;jsessionid</code>. -</li> -<li> -Automatically determining the size of the shared memory segment needed -to accommodate all workers. -</li> -<li> -New connection establishment timeout <code>socket_connect_timeout</code>. -</li> -<li> -New timeout <code>connection_acquire_timeout</code> for acquiring a free connection from -the pool. -</li> -<li> -Improved retry handling by adjusting the meaning of the attribute <code>retries</code> for -AJP workers and for load balancers and by adding the new <code>retry_interval</code>. -</li> -<li> -Allowing the web server to provide error pages instead of Tomcat. -</li> -</ul> -</p> -</subsection> -</section> -</body> -</document> |
