JSF caching of javascript, css, etc

In order to have static resources cached change in web.xml from
    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>

to

    <context-param>

        <param-name>javax.faces.PROJECT_STAGE</param-name>

        <param-value>Production</param-value>

    </context-param>

This will allow caching of static resources fro 10 minutes;in order to change the default value add another context parameter: com.sun.faces.defaultResourceMaxAge (the default value of this parameter is 604800 ~ 10 mins)
