Get Last Modified Date Of A Web Page
For getting the last modified date of a web page, just paste following statement of javascript to your browser address window and execute. This works for mozilla, IE i am not sure about
javascript:alert(document.lastModified)
It gives the time at which page is loaded in case if it is disabled or if it is dynamically created.
