<p>Choosing a connector to use with Tomcat can be difficult. This page will

<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>

|
|
<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>
