how to know the sites visited earlier, if it has been deleted from the history.?
Do any of these help
Are you able to give a bit more detail about what it is you are trying to do. I was not sure so took a rather shotgun type approach and posted a bunch of links hoping one may answer your question.
By default History is saved unless you are in Private Browsing, but there are a few options for changing various settings and deleting History Items or lists.
Please read the above linked articles then post back with how you get on and whether you need any more help.
