    Today we’re updating our platform roadmap with a few more features that we’ve started working on: Responsive Images: image srcset To take advantage of high resolution screens, it’s desirable to provide higher resolution image resources.

    This Week in Privacy

    • 15 Comments
    In the last ten years Microsoft has invested heavily in user privacy. Just like security, privacy considerations are baked into every Microsoft product.

    Rely on Declarative Security Features in the Browser

    • 15 Comments
    Cutting edge web applications push the boundaries of the web development model. In the security space, this raises an interesting question – who owns security for a web application built on a complex platform hierarchy? Is it the application at the top of the stack, the intermediate platform component, or the browser itself? We believe that web application security is a shared responsibility between the browser client, web platform components (such as ASP.Net), and web applications themselves...

    CreateURLMoniker Considered Harmful

    • 15 Comments
    While working on IE7 application compatibility, we’ve seen many cases of interesting and strange invalid file URIs. I believe a substantial amount of responsibility for the confusion over file URIs lies with the deprecated urlmon.dll function CreateURLMoniker. This function is used by Windows application developers mainly to convert a string URI into an object that can be used to obtain the data represented by the URI. CreateURLMoniker does a couple of horrible things to file URIs that if misused...
