Filter redirect not reaching to spring Controller

Hyn, I have a servlet filter,

in first step:

I am checking url from particualr action and based on that creating a new url, redirecting

String redirectURL = httpResponse.encodeRedirectURL( shopUrl + "/catalogPreview?setPreviewDate=090000");

LOG.info("RUN PREVIEW: " + redirectURL + " | IP " + httpRequest.getRemoteAddr());

httpResponse.sendRedirect(redirectURL);

return;

and return then the filter is again called with previously assemble url and let it through going through filter chain

else
{
    // proceed filters
    filterChain.doFilter(httpRequest, httpResponse);
}

the new url should reach the spring controller here is spring annotation mapping for review

@Controller
@RequestMapping(value = {"/{testId:.*}/", "/lalanium","/catalogPreview"})
public class TestPageController extends AbstractTestPageController
{

the new URL is also visible in header but getting 400 error... am I missing some step? please share
