I'm using Tomcat 8 and Tuckey urlrewrite to remove ".jsp" from my web page URLs. Its working fine but I noticed the X-Frame-Options in the response header are not present when urlrewrite redirects from a page. mysite.com/Home translates to mysite.com/Home.jsp but the X-Frame options are not set. They are set for all the pages that I exclude from urlrewirte such as mysite.com/picture.png. Any guidance would be appreciated.
Web.xml

urlrewrite.xml:

So this turns out not to be a problem with URL Rewrite but a missing for the httpSecurityHeader filter that contained the x-frame-options. After adding the mapping "/*" every file now has the antiClickJacking options set. Below is the web.xml settings that make that happen.
<filter>
<filter-name>httpHeaderSecurity</filter-name>
<filter-class>org.apache.catalina.filters.HttpHeaderSecurityFilter</filter-class>
<init-param>
<param-name>antiClickJackingOption</param-name>
<param-value>SAMEORIGIN</param-value>
</init-param>
<init-param>
<param-name>antiClickJackingEnabled</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>httpHeaderSecurity</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
