Below are steps to implement Caching on Tomcat server

  1. You will have to download "Cache Filter" jar file from the below location. http://code.google.com/p/cache-filter/downloads/list

  2. Put that jar file in tomcat/webapps/ROOT/WEB-INF/lib location.

  3. Edit tomcat/webapps/ROOT/WEB-INF/web.xml file and add filter and filter-mapping properties as mentioned below.

    <filter>
<filter-name>imagesCache</filter-name>
<filter-class>com.samaxes.filter.CacheFilter</filter-class>
<init-param>
<param-name>static</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>expirationTime</param-name>
<param-value>2592000</param-value>
</init-param>
</filter>
<filter>
<filter-name>cssCache</filter-name>
<filter-class>com.samaxes.filter.CacheFilter</filter-class>
<init-param>
<param-name>expirationTime</param-name>
<param-value>604800</param-value>
</init-param>
</filter>
<filter>
<filter-name>jsCache</filter-name>
<filter-class>com.samaxes.filter.CacheFilter</filter-class>
<init-param>
<param-name>private</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>expirationTime</param-name>
<param-value>216000</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>cssCache</filter-name>
<url-pattern>*.css</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>jsCache</filter-name>
<url-pattern>*.js</url-pattern>
</filter-mapping>

  4. Restart Tomcat and check the expires headers on browsers.
