+<p>Choosing a connector to use with Tomcat can be difficult. This page will
+list the connectors which are supported with this Tomcat release, and will
+hopefully help you make the right choice according to your needs.</p>

+
+<section name="HTTP">
+
+<p>The HTTP connector is setup by default with Tomcat, and is ready to use. This
+connector features the lowest latency and best overall performance.</p>
+
+<p>For clustering, an HTTP load balancer <b>with support for web sessions stickiness</b>
+must be installed to direct the traffic to the Tomcat servers. Tomcat supports mod_proxy
+(on Apache HTTP Server 2.x, and included by default in Apache HTTP Server 2.2) as the load balancer.
+It should be noted that the performance of HTTP proxying is usually lower than the
+performance of AJP, so AJP clustering is often preferable.</p>
+
+</section>
+
+<section name="AJP">
+
+<p>When using a single server, the performance when using a native webserver in
+front of the Tomcat instance is most of the time significantly worse than a
+standalone Tomcat with its default HTTP connector, even if a large part of the web
+application is made of static files. If integration with the native webserver is
+needed for any reason, an AJP connector will provide faster performance than
+proxied HTTP. AJP clustering is the most efficient from the Tomcat perspective.
+It is otherwise functionally equivalent to HTTP clustering.</p>
+
+<p>The native connectors supported with this Tomcat release are:</p>
+<ul>
+<li>JK 1.2.x with any of the supported servers</li>
+<li>mod_proxy on Apache HTTP Server 2.x (included by default in Apache HTTP Server 2.2),
+with AJP enabled</li>
+</ul>
+
+<p><b>Other native connectors supporting AJP may work, but are no longer supported.</b></p>
