How to enable browser caching of static content(images, css, js) with Tomcat?

Question

How to enable browser caching of static content(images, css, js) with Tomcat? Preferable solution will be editingspring MVC config files or web.xml

Answer 1

try (with changing the values)

<mvc:resources mapping="/static/**" location="/public-resources/" 
       cache-period="31556926"/>
<mvc:annotation-driven/>

You can also use an interceptor:

<mvc:interceptors>
   <mvc:interceptor>
    <mvc:mapping path="/static/*"/>
    <bean id="webContentInterceptor" 
         class="org.springframework.web.servlet.mvc.WebContentInterceptor">
        <property name="cacheSeconds" value="31556926"/>
        <property name="useExpiresHeader" value="true"/>
        <property name="useCacheControlHeader" value="true"/>
        <property name="useCacheControlNoStore" value="true"/>
    </bean>
   </mvc:interceptor>
</mvc:interceptors>

See the MVC docs

Answer 2

If Spring 3.0 is being used, <mvc:resources> is one way to implement caching of static resources. This link has some documentation.
