Hi Jakob,
Thanks for your response.
The following 2 lines of code work perfectly according to my requirement of
forward.
*RequestDispatcher rd =
request.getRequestDispatcher("/content/geometrixx/en/products.html"); *//here
request is SlingHttpServletRequest since it is a sling servlet.
*rd.forward(request, response);*
this code properly resulting in forwarding the request to products page and
does not change the url in the browser.
*Also one more thing I wanted to discuss is the use of servlet vs filter.
Apache webserver hitting my servlet/filter which routes the calls
accordingly to webapp or forward to CQ page logic. I was not able to work
my request dispatcher code with Filter and shifted to Servlet. Does
exposing Servlet vis a vis filter to Apache webserver would have any
security implications?*
*I am not going the Resource route, as Iam not sure how to resolve the
resource with html extension. Only I am able to resolve until the node path
but not the extension .html path.,*
Resource resource =
slingRequest.getResourceResolver().getResource("/content/geometrixx/en/products");
RequestDispatcherOptions requestDispatcherOptions = new
RequestDispatcherOptions();
RequestDispatcher requestDispatcher =
slingRequest.getRequestDispatcher(resource,requestDispatcherOptions);
requestDispatcher.forward(slingRequest, response);
I am getting to that jcr node, but not able to render the products page.
What extra code handling do I need to do render the products,html page. It
is changing the url also in the browser.
*When I hit the servlet
http://localhost:4502/myvanity/forwardVanityresults in the change of
the browser url as
http://localhost:4502/content/geometrixx/en/products/ resulting in the
response as follows:*
products
- .. <http://localhost:4502/content/geometrixx/en>
-
jcr:content<http://localhost:4502/content/geometrixx/en/products/jcr:content>
- triangle<http://localhost:4502/content/geometrixx/en/products/triangle>
- square <http://localhost:4502/content/geometrixx/en/products/square>
- circle <http://localhost:4502/content/geometrixx/en/products/circle>
- mandelbrot<http://localhost:4502/content/geometrixx/en/products/mandelbrot>
Best Regards,
Durga
