Here's an interesting situation.
The website being scanned was http://peacockmedia.software. As you can see, the link found during the crawl is a link to a page on peacockmedia.co.uk . That looks like an external link, and so Scrutiny has marked it as an external link, therefore checked its status but not followed it.
However, it redirects to a url on peacockmedia.software - so the ultimate destination is an internal one.
There are a bunch of pages which will only be discovered if this link is considered internal.
(the pages are old manual pages - I want them to be orphaned, but that's beside the point...)
The question is - should Integrity and Scrutiny consider that link *internal* (and therefore follow it and discover more internal pages) or *external* (so it's checked but then is a dead end). Remember that the original link is to an external domain.
