java - Send specific headers on MIME-type response in Apache Tomcat -


i have apache tomcat server running. if have like:

webapp/     image1.png

then, can access using:

example.com/image1.png

which perfect, except don't have control on headers being sent. wish send specific expires header mime-types (like, image/png). these headers static, don't mind if have specify in xml file , cannot dynamic.

is possible apache tomcat? other obvious way read file , output browser appropriate headers, think might overkill.

use tomcat filters applying headers.

<web-app ...>     ...     <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>     ...  </web-app>
