我们正在使用 JSF 2.0 / Richfaces 4.2.2 创建一个应用程序。该页面在 IE9（3-4 秒）中加载速度很快，但在 Chrome 中加载速度非常慢。

看看网络，问题似乎是对于大多数 JSF 和 Richfaces 资源，浏览器会收到 304 响应，但最终获得这些资源需要很长时间（我说的是几分钟）。

我的 web.xml：

<context-param>
        <description>
            Set the max time in miliseconds set on the "Expires" header for a resource rendered by the default ResourceHandler.
        </description>
        <param-name>org.apache.myfaces.RESOURCE_MAX_TIME_EXPIRES</param-name>
        <param-value>2592000000</param-value><!-- 30 Days -->
    </context-param>

    <!-- RichFaces -->
    <context-param>
        <description>Defines in seconds how long streamed back to browser resources can be cached.</description>
        <param-name>org.ajax4jsf.DEFAULT_EXPIRE</param-name>
        <param-value>2592000</param-value><!-- 30 Days -->
    </context-param>

 <context-param>
        <param-name>org.richfaces.resourceOptimization.enabled</param-name>
        <param-value>false</param-value>
    </context-param>
    <context-param>
        <param-name>org.richfaces.LoadScriptStrategy</param-name>
        <param-value>ALL</param-value>
    </context-param>
    <context-param>
        <param-name>org.richfaces.LoadStyleStrategy</param-name>
        <param-value>ALL</param-value>
    </context-param>
    <context-param>
        <!-- If org.richfaces.LoadScriptStrategy is set to ALL, this should be false -->
        <param-name>org.ajax4jsf.COMPRESS_SCRIPT</param-name>
        <param-value>false</param-value>
    </context-param>
