I can't set any session attributes, because I get a new HttpSession on every request. To validate this, I added <%=slingRequest.getSession().getId()%> to /apps/geometrixx/components/homepage/content.jsp. Now I can see the http session id on every request to http://localhost:4502/editor.html/content/geometrixx/en.html. And I can see, this Id changes for every request so it makes no sense to set any session attributes like request.getSession().setAttribute("...", "....").
Can anybody tell me, how to get a valid http session which does not change for every single request?
