Some Web pages cannot be loaded only by URL. These pages require session state, e.g. entering a password, logging in, and then clicking a link to get to the page. When you try to capture one of these pages, EagleFiler will import the site’s login page, since that’s what the server produces when EagleFiler requests the URL. (An easy way to see that this has happened is to set Notification Center to show EagleFiler’s notifications as banners so you can see the thumbnail preview of each Web page that you capture, to check whether it looks right.)
To import these types of pages, see the Private Web Pages section.
