IE10 Packs IE9, IE8, IE7, and IE5 Rendering Modes
Internet Explorer 10 can seamlessly “go back in time” and render websites as if it was one of its predecessors, such as IE5, IE7, IE8, IE9.Not that this is anything new when it comes down to major IE iterations. Microsoft remains committed to supporting legacy websites with new versions of IE just as it still supports legacy applications with fresh Windows releases.Of course, while the IE team has always acted on a mantra of not breaking the web with new IE releases, but packing multiple rendering modes into the browser
There are times when you need to view the content of a website while your computer is not connected to the internet. To do that, you need to Work Offline. This tutorial shows how to do this in Internet Explorer 8.On Internet Explorer's File menu is a "Work Offline" item that toggles Internet Explorer between online and offline modes of operation.
When Internet Explorer is set to the offline mode, clicking on hyperlinks and updating channels that refer to online content causes a dialog box to appear asking if Internet Explorer should connect to the network to download the requested content. If the connection is made, Internet Explorer will automatically change from offline mode to online mode for the remainder of the session or until you reselect Work Offline.
