- <ul><li>Use "asset:" or "context:" <a shape="rect" href="component-parameters.html">binding prefixes</a> for all links to static resources (images, CSS, JavaScript).</li><li>Make sure that your firewall, proxy server, load balancer, front-end web servers, and app servers all allow caching of static resources.</li><li>Ensure "cache-control" and "vary" HTTP headers are set correctly for your static resources.</li><li>Use a client-based tool (like Firebug) to examine the requests that your browser makes as you navigate through the site.

+<h3>Related Articles</h3>
-<p>For web applications, <strong>clustering</strong> is a load-balancing technique in which multiple application servers are set up to behave as one big server. Generally this requires replicating HttpSession data across the servers, to ensure that a user's web interactions will continue without interruption regardless of which server handles the next request. Session replication achieves very high reliability, but it incurs an extra performance cost (due to the serializing and deserializing of session data and the extra network traffic required).</p>

-<p>In contrast, <strong>Sticky Sessions</strong> (also called <em>session persistence</em> or <em>sticky persistence</em>) is a load balancing technique in which each session is assigned to a particular server for the duration of the session. This approach doesn't require copying HTTPSession data between servers, so it's very scalable. But if a server goes down, all of its sessions are lost.</p>
