Add custom headers easily to your Tomcat response using param-name and param-value tags in web.xml

Installation

• Put response-header-filter.jar in your $CATALINA_HOME/lib directory
• Edit your web.xml located in $CATALINA_HOME/conf
• Add the following filter and filter mapping inside <web-app> tag:

  <filter>
      <filter-name>ResponseHeaderFilter</filter-name>
      <filter-class>pl.hordyjewiczmichal.ResponseHeaderFilter</filter-class>
      <init-param>
          <param-name>Your-Header-1</param-name> <!-- put your any header name -->
          <param-value>
              your value1
              your value2
              your value3
          </param-value> <!-- put your header value(s) separated by a new line  -->
      </init-param>
      <init-param>
          <param-name>Your-Header-2</param-name>
          <param-value>some other value</param-value>
      </init-param>
  </filter>
  <filter-mapping>
      <filter-name>ResponseHeaderFilter</filter-name>
      <url-pattern>/*</url-pattern> <!-- choose where header will be added -->
  </filter-mapping>

In <init-param> use <param-name> tag to add your custom header and below use <param-value> to add value to your header. You can use multiple values for your header in <param-value> - just separate them by a new line.
