| 19 | <p>For clustering, a HTTP load balancer <b>with support for web sessions stickiness</b>
|
| 20 | must be installed to direct the traffic to the Tomcat servers. Tomcat supports mod_proxy
|
| 21 | (on Apache HTTP Server 2.x, and included by default in Apache HTTP Server 2.2) as the load balancer.
|
| 22 | It should be noted that the performance of HTTP proxying is usually lower than the

| 23 | performance of AJP, so AJP clustering is often preferable.</p>

|
| 27 | <p>When using a single server, the performance when using a native webserver in
|
| 28 | front of the Tomcat instance is most of the time significantly worse than a
|
| 29 | standalone Tomcat with its default HTTP connector, even if a large part of the web
|
| 30 | application is made of static files. If integration with the native webserver is
|
| 31 | needed for any reason, an AJP connector will provide faster performance than
|
| 32 | proxied HTTP. AJP clustering is the most efficient from the Tomcat perspective.
|
| 33 | It is otherwise functionally equivalent to HTTP clustering.</p>
