I have a high number of page views on my Page Not Found page. I have used the Previous Page report to figure out that some of our pages may have bad links, but the high majority of the page views have my Page Not Found as the entry page. We recently migrated our site and I think users may have old bookmarks. I can do redirects if I know what the URLs are. Is there any way to capture what URL is being typed in/bookmarked that leads to the Page Not Found?
