Tiles and Filters

[coffeejoy lung]

Does anyone have issue with filters getting call multiple times when a page is render from tiles definition?

web.xml

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

tiles.xml

  <definition name="default" template="/WEB-INF/layouts/default.jspx">
		<put-attribute name="menu" value="/WEB-INF/views/menu.jspx" />
	</definition>  

IpRegionFilter

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException,
			ServletException
	{
		HttpServletRequest request = (HttpServletRequest) req;

		// Get the IP address of client machine.
		String ipAddress = request.getRemoteAddr();

		// Log the IP address and current timestamp.
		// query region by IP range
		System.out.println("IP " + ipAddress + ", Time " + new Date().toString());

		chain.doFilter(req, res);
	}    

When the default page gets rendered, it would system out multiple times.
Is there anyway to just call filter once per page?

Thanks in advance.
