    Asynchronous Programming in JavaScript with “Promises”

    • 18 Comments
    Asynchronous patterns are becoming more common and more important to moving web programming forward. They can be challenging to work with in JavaScript. To make asynchronous (or async) patterns easier, JavaScript libraries (like jQuery and Dojo) have added an abstraction called promises (or sometimes deferreds). With these libraries, developers can use promises in any browser with good ECMAScript 5 support. In this post, we’ll explore how to use promises in your web applications using XMLHttpRequest2...

    HTTP/2: The Long-Awaited Sequel

    • 18 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...

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

    • 17 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...

    Debugging Web Workers in IE10

    • 17 Comments
    With Web Worker s, Web applications can be more responsive by offloading long-running, complex JavaScript algorithms to run in the background. IE10 includes a complete and predictable debugging experience for JavaScript executing within both the Web page and in Web workers. In IE10, we’ve enhanced the F12 tools to be aware of the new script contexts created for every Web worker. When you start debugging (by clicking the Start debugging button within the F12 tools), you’re attaching to...

    Add-on Performance Part 3: Optimizing Add-on Startup Performance

    • 17 Comments
    In the first post of this series, we described how add-ons can decrease IE’s performance during tab creation. Many users with add-ons enabled have noticed a performance improvement when they open new tabs after disabling their add-ons. We also walked you through how to measure add-on performance and identify areas of impact using the Windows Performance Tools . In this post, we delve into methods and best practices developers can use to improve their add-ons’ start-up performance,...

    MIME-Handling Changes in Internet Explorer

    • 17 Comments
    Each type of file delivered from a web server has an associated MIME type (also called a “content-type”) that describes the nature of the content (e.g. image, text, application, etc). Back in Internet Explorer 8, we made a few changes to IE’s MIME-sniffing feature that attempts to determine the actual content-type for each downloaded resource. In this post, I discuss how recent changes to IE further improve MIME-handling and make browsing more secure. Certain HTML elements (LINK and SCRIPT in particular...

    Performance: Profiling how different web sites use browser subsystems

    • 17 Comments
    When we first showed IE9 at the Professional Developers Conference last fall , we discussed how real world browser performance involves many different subsystems. Different websites use these subsystems in different ways, and to build a fast real world browser you have to start by understanding these overall patterns. This post provides an inside look at how these subsystems impact the performance of five real world websites. We use Internet Explorer 8 for this analysis, and as IE9 approaches we...

    Hi, I’m B. Ashok, the Product Unit Manager for Web Development Tools . As mentioned in my earlier post last summer, we have removed the DHTML Editing Control from Windows Vista as part of making the operating system more secure. One application that used the DHTML Editing Control in the past was OWA (Outlook Web Access). We have issued a required update to both Exchange 2000 and 2003 that enables OWA support for IE7 in Windows Vista. However if your server does not have this update applied, you...

    IE7 Dialog Sizes - A Quick Update

    • 17 Comments
    This is just a follow up to my recent post about dialog sizing in IE7 . Based on your feedback regarding the minimum dialog height restrictions, my team re-evaluated our position and changed the minimum height from 150 to 100 pixels. We think this change: Reduces application compatibility issues where dialogs were coded to the IE6 minimum height Is more consistent with other browsers’ minimum height providing more consistency for content developers Again, we appreciate your constructive...

    RSS Secure by Design

    One of the reasons we went to Blackhat last month was to show how the Security Development Lifecycle (SDL) has changed the way that Microsoft builds products. I talked about how we’re reducing attack surface with features like ActiveX opt-in, improving code quality and building-in Defense in Depth with Protected Mode . I didn’t get a chance to cover the new RSS feed support but I think the RSS team’s work is a great example for anyone building a new client to handle RSS feeds and a case study in...
