This document summarizes the request and response process in Joomla. It explains that when a request is made, Joomla loads the framework and initializes the application. It then fires the onAfterInitialise event, which is used by system plugins. It routes the request and fires the onAfterRoute event, then dispatches the request and fires onAfterDispatch. After rendering, it fires onAfterRoute which plugins like cache and SEF use. Finally, it sends the response.
