  • Blog Post: Braindump: Feature Control Keys and URLActions

    Note: The “brain dump” series is akin to what the support.microsoft.com team calls “Fast Publish” articles—namely, things that are published quickly, without the usual level of polish, triple-checking, etc. I expect that these posts will contain errors, but I also expect...
  • Blog Post: Brain Dump: Random Tidbits

    This post contains random IE-related tidbits for which there’s either not enough material or time to write a full post. I expect to revisit and expand this list from time to time. Case-Sensitivity in Cross-Frame Scripting of File URIs Same-Origin-Policy controls how script running in web...
  • Blog Post: HTTPS and Keep-Alive Connections

    As we explore network performance on the “real-world web”, one bad pattern in particular keeps recurring, and it’s not something that our many IE9 Networking Performance Improvements alone will resolve. The bad pattern is the use of Connection: close semantics for HTTPS connections...

  • Blog Post: Preventing Automatic Hyperlinking in ContentEditable HTML

    Today, a question from the mail bag… Q: Is there a way to stop IE from “auto-magically” recognizing and creating hyperlinks inside HTML? First, a bit of context. Web developers can use the ContentEditable property to allow users to edit part of a HTML page. This mechanism is often used to allow...
  • Blog Post: WebOCs, popups, and the default browser

    Applications which host the WebOC (Web Browser control) may choose to support popups and new windows by hooking the NewWindow3 event and returning in ppDisp a pointer to a new, hidden, non-navigated WebBrowser object or InternetExplorer object. If such an interface is returned, the browser so provided...
