    More on Simple List Extensions

    • 20 Comments
    There are two posts on the RSS team blog about the use of the Simple List Extensions , which have been implemented by IE7 and the Windows RSS Platform. The first is Simple List Extensions in action , and it shows examples of live sites (like Amazon.com, eBay and Yahoo) using the RSS extensions to add sorting and filtering capabilities to their feeds. The second is a longer post on Understanding Lists and SLE , which explains why RSS list feeds are useful and how they work (with diagrams!)....

    Slipstreaming IE8

    • 20 Comments
    As James and I mentioned in our blog post What’s coming in IE8 for IT Pros? , IE8 can now be slipstreamed into Vista and Window Server 2008 OS images. If you manage the desktop images for your organization, slipstream saves you time by simplifying the task of adding Internet Explorer 8 and any IE updates. If you’re adding Internet Explorer 7 to a Windows XP image you’ll typically install XP and then add IE7 before capturing the image -this can take 2 hours! With IE8 and Windows Vista, you are able...

    How I'll Judge IE7 Security

    • 20 Comments
    As an engineer, I’m proud of the protections we delivered by finishing IE7 but I want to set your expectations that we didn’t and, never will, reach perfection. There have been a few posts on ways to steal data or spoof URLs in IE7 but they really don’t detract from a very simple truth: IE7 will be more secure than IE6 was and frankly, comparisons to other browsers are still too early to be objective. I want to talk about the “big picture” of how I will judge the progress we made in IE7 and how...

    Dealing with List Feeds

    • 20 Comments
    Recently, I received an interesting customer question I thought I would share. A web developer presented me with the following scenario: his web application lets users create and manage a list of items, and this list is exposed as a feed so users can be updated when it changes. However, after the user deletes an item using the web application, that item is still present in the feed view of the RSS aggregator. Since the feed is supposed to correctly reflect the state of the user’s item list, this...

    After downloading the Internet Explorer Cumulative Security Update for May 2007, some users have experienced an unexpected “Save File” security dialog upon launching Internet Explorer. This might occur when the “Temporary Internet Files” folder is moved to a custom location and Internet Explorer does not have appropriate access rights to the new folder location. The Internet Explorer Team is currently investigating appropriate solutions for this user scenario. For your security, we strongly recommend...

    JavaScript: Same Code, and a Standardized Test Suite

    • 20 Comments
    Being all in with HTML5 means being committed to enabling developers to use the Same Markup on the Web, and that includes the same JavaScript code.

    Another Follow-up on HTML5 Video in IE9

    • 20 Comments
    In previous posts , we described why IE9 will support H.264-encoded HTML5 video. Microsoft and other browser providers see hardware support, customer and partner readiness , and intellectual property rights as key factors making H.264 an excellent choice for video encoding and playback. These posts generated a significant amount of support and suggestions. This feedback together with today’s industry announcements create a good opportunity to follow up and provide more information about HTML5...

    Enabling new interoperable panning experiences through the CSS Scrolling Snap Points Specification

    • 20 Comments
    Today, we submitted a new proposal to the W3C, CSS Scrolling Snap Points, designed to enable fast and fluid panning experiences for touch and other input devices, based on APIs introduced in IE10 and improved in IE11. These APIs enable developers to more easily build panning experiences such as paginated content and scrolling photo galleries that are perfect for touch and work just as easily with mouse, keyboard, or trackpad. A great example of this experience is the MSN homepage optimized for Windows...

    Certificate reputation, a novel approach for protecting users from fraudulent certificates

    • 19 Comments
    At the IETF in London last week, we presented a proposal called Certificate Reputation for detecting fraudulent certificates, in order to protect you from attackers that could have stolen a site’s identity. This prevents malicious sites from phishing your personal information like passwords, bank account numbers, credit card numbers etc. Recent attacks against public and Microsoft CAs (e.g. the DigiNotar and Comodo attacks) led us to develop mechanisms that protect you from such threats. Background...

    HTTP/2: The Long-Awaited Sequel

    • 19 Comments
    Ready to speed things up? Here at Microsoft, we’re rolling out support in Internet Explorer for the first significant rework of the Hypertext Transfer Protocol since 1999. It’s been a while, so it’s due. While there have been lot of efforts to streamline Web architecture over the years, none have been on the scale of HTTP/2. We’ve been working hard to help develop this new, efficient and compatible standard as part of the IETF HTTPbis Working Group. It’s called, for obvious reasons, HTTP/2...

    Enhanced Memory Protections in IE10

    • 19 Comments
    Internet Explorer 10 introduces significant improvements in memory protections to help make vulnerabilities harder to exploit, helping to keep users safe on the sometimes-hostile Web. These improvements will increase the difficulty and development cost of exploits, making life harder for the bad guys. While socially-engineered malware is the primary way that bad guys get their code onto victims’ computers, that is largely because browser vulnerabilities have become less common and harder...
