无法通过ExpiresFilter为JavaScript文件添加过期或缓存控制响应标头

Question

我有一个运行在Windows上的Tomcat 8.0.36上的网站。我跟踪了这个链接

https://tomcat.apache.org/tomcat-8.0-doc/config/filter.html

若要添加过期和缓存控制响应标头，请执行以下操作。以下是我所做的：

<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 minutes</param-value>
 </init-param>
 <init-param>
    <param-name>ExpiresByType text/css</param-name>
    <param-value>access plus 10 minutes</param-value>
 </init-param>
 <init-param>
    <param-name>ExpiresByType application/javascript</param-name>
    <param-value>access plus 10 minutes</param-value>
 </init-param>
</filter>
...
<filter-mapping>
 <filter-name>ExpiresFilter</filter-name>
 <url-pattern>/*</url-pattern>
 <dispatcher>REQUEST</dispatcher>
</filter-mapping>

在我的测试之后，javascript的正确init代码似乎应该是（x-javascript）：

 <init-param>
    <param-name>ExpiresByType application/x-javascript</param-name>
    <param-value>access plus 10 minutes</param-value>
 </init-param>
