由 对着背影说爱祢 提交于 2019-12-13 15:30:28

I have seen few components( most of them are page or top level components) in CQ5 which are having more than one jsp under a single component(e.g page component have page.jsp, body.jsp, header.jsp similary redirect component have redirect.jsp, body.jsp, content.jsp) . So i wanted to ask in what scenarios, we will be having multiple jsp's
