This can be accomplished using a Tomcat filter. Simply edit your <YellowfinInstall>/appserver/webapps/ROOT/WEB-INF/web.xml file and add the following filter block to your file.

<filter>
    <filter-name>ExpiresFilter</filter-name>
    <filter-class>org.apache.catalina.filters.ExpiresFilter</filter-class>
    <init-param>
        <param-name>ExpiresByType image</param-name>
        <param-value>access plus 10 days</param-value>
    </init-param>
    <init-param>
        <param-name>ExpiresByType text/css</param-name>
        <param-value>access plus 10 hours</param-value>
    </init-param>
    <init-param>
        <param-name>ExpiresByType application/javascript</param-name>
        <param-value>access plus 10 minutes</param-value>
    </init-param>
    <!-- Let everything else expire immediately -->
    <init-param>
        <param-name>ExpiresDefault</param-name>
        <param-value>access plus 0 seconds</param-value>
    </init-param>
</filter>
