Page_UnLoad in ASP.NET architecture

The Page Life Cycle Events

Page_UnLoad : The page is unloaded from the memory, and the Response object is sent to the browser in the Page Unload event. You can override this method to perform your necessary cleanup activities. According to MSDN, “Unload is called after the page has been fully rendered, sent to the client, and is ready to be discarded. At this point, page properties such as Response and Request are unloaded and any cleanup is performed.”
