google app engine - web.xml filter won't run on static content

Question

Does anyone know why a web.xml filter wouldn't be run when serving a welcome file, or any static content? It seems to only run on URLs that are mapped to a servlet. How can I get the filter functionality on static content?

Here's what I'm using:

  <filter>
     <filter-name>myFilter</filter-name>
     <filter-class>com.domain.project.server.service.MyFilter</filter-class>
  </filter>

 <filter-mapping>
    <filter-name>myFilter</filter-name>
    <url-pattern>/*</url-pattern>
 </filter-mapping>

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

 <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

  <welcome-file-list>
    <welcome-file>WelcomeFile.html</welcome-file>
  </welcome-file-list>
