Duplicate page for locale pages while using sling:alias property

[sachinn20956098]

We have locale specific pages and we are using sling:alias property to have language specific page name . But the problem is both the urls are publicly accessible : 1) with sling:alias name 2) with original page name.

Example :

page is /content/brand/de/home.html

          -> This home page node has been set a sling:alias property of "zuhause"

Ideally end user should be seeing the page URL : /content/brand/de/zuhause.html

But currently both the urls are serving the content : /content/brand/de/home.html  and /content/brand/de/zuhause.html

How to block the original page url and serve only the locale specific (with sling:alias) url  ?

Hi,

You can block/redirect url either by server redirect or AEM sling:mapping.

Well, technically it's just an alias, so both ways are ok to use.

If I understand you correctly, you would like to have the page available only via it's alias, not with it's "real" name. You could implement a request filter, which checks if the requested resource is requested via it's real name and then do a redirect to its alias'ed name (or just return a 404 ...). Shouldn't be a big problem to implement that. And of course adapting the linkrewriter to only use the alias when building links.

On the other hand it find it always quite useful if I can just take the URL in the browser and look up that name in the content tree (CRXDE); that's getting harder if you only use aliases.

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() {

    }

}

The request and response object are inheriting from HttpServletRequestWrapper and HttpServletResponseWrapper which have a getResource() method.
