java - filter not executing on static content request -

-

i'm trying implement making gwt apps crawlable, crawlfilter isn't being executed, ever. doing wrong? static content not subject filters?

<web-app>   <!-- crawling servlet filter -->   <filter>     <filter-name>ajaxcrawlfilter</filter-name>     <filter-class>com.bitdual.server.crawlservlet</filter-class>   </filter>    <filter-mapping>     <filter-name>ajaxcrawlfilter</filter-name>     <url-pattern>/*</url-pattern>   </filter-mapping>    <!-- default page serve -->   <welcome-file-list>     <welcome-file>index.html</welcome-file>   </welcome-file-list>  </web-app>

static content served entirely different infrastructure (like cdn) wouldn't surprised if filters not executed on content hosted statically.
