Hi Jakob,
Thanks for your response.
First of all the pretty standard requestDispatcher, i was trying with
Filter.My filter was registered with Ext.HttpService and did not work. The
same code worked well with the Sling Servlet.
ExtHttpService service = (ExtHttpService) context.getService(sRef);
service.registerFilter(new VanityUrlFilter(), "/testVanityFilter", null, 0,
null);
.
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
RequestDispatcher requestDispatcher =
request.getRequestDispatcher("/content/geometrixx/en/products.html");
requestDispatcher.forward(request, response);
}
http://localhost:4502/testVanityFilter was yielding me the response
*The requested URL /content/geometrixx/en/products.html was not found on
this server.*
When I look into the logs, I could see this.
*30.04.2012 12:39:44.854 *INFO* [0:0:0:0:0:0:0:1 [1335807584851] GET
/content/geometrixx/en/products.html HTTP/1.1]
org.apache.sling.engine.impl.SlingRequestProcessorImpl service: Resource
/testVanityFilter not found*
*I have put the same code in the Sling Servlet and could see that the
request is forwarded to the products page successfully with no url change
in the browser which is desired behaviour.*
My scenario is Apache server would hit my filter or servlet now, and
filter/servlet would look for whether its a CQ content page or my webapp
page and then if it is a CQ page, forward it to CQ page as above. Would
there be any difference from the security perspective to use the servlet
vis a vis filter.
Second thing is I have found examples using the SlingHttpServletRequest and
the usage. I was not sure how to call the content/geometrixx/en/products.html.
Of course with out using the SlingHttpServletRequest also I am able to
serve the same using servletRequest object.
I just want to deal with CQ pages using SlingHttpServletRequest and was not
able to solve with SlingHttpServletRequest.
SlingHttpServletRequest slingRequest = (SlingHttpServletRequest)request;
Resource resource =
slingRequest.getResourceResolver().getResource("/content/geometrixx/e
n/products.html");
RequestDispatcherOptions requestDispatcherOptions = new
RequestDispatcherOptions();
RequestDispatcher requestDispatcher =
slingRequest.getRequestDispatcher(resource,requestDispatcherOptions);
Best Regards,
Durga
