Thanks Jörg !
I tried implementing a Custom Filter to achieve this functionality , but I am facing an issue : Request and Response objects are of type org.apache.sling.i18n.impl.I18NFilter$I18NSlingHttpServletRequest and they can not be cast to SlingHttpServletRequest and this request type is not an instance of SlingHttpServletRequest.
I tried ranking this custom filter higher than the CQ i18n filter but that is not helping.
@Service(Servlet.class)
@SlingFilter(
label = "Custom Redirect Filter",
description = "Custom Utility Redirect Filter",
metatype = false,
generateComponent = true,
generateService = true,
order = 100,
scope = SlingFilterScope.REQUEST)
public class CustomRedirectFilter implements Filter {
private static final org.slf4j.Logger log = LoggerFactory.getLogger(CustomRedirectFilter.class.getName());
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
if (!(request instanceof SlingHttpServletRequest)) {
chain.doFilter(request, response);
return;
}
log.info("============================================================");
log.info("Inside custom redirect filter");
log.info("============================================================");
final SlingHttpServletResponse slingResponse = (SlingHttpServletResponse) response;
final SlingHttpServletRequest slingRequest = (SlingHttpServletRequest) request;
final Resource resource = slingRequest.getResource();
if(resource.getResourceType().equals("cq:Page"))
{
PageManager pageManager = resource.getResourceResolver().adaptTo(PageManager.class);
Page page = pageManager.getPage(resource.getPath());
String templatePath = page.getContentResource().getValueMap().get("cq:template").toString();
if(templatePath.equals("/apps/custom/test-com/templates/default"))
{
slingResponse.setStatus(HttpServletResponse.SC_OK);
slingResponse.setHeader("Location", "/content/test-com/en/error-404.html");
slingResponse.setHeader("Connection", "close");
return;
}
}
chain.doFilter(slingRequest, slingResponse);
}
@Override
public void destroy() {
}
}
