Yesterday, Microsoft revealed the brand new browser, codenamed “Project Spartan” which they have been working since last year. This new browser is designed for Windows 10 devices to offer more interoperable, reliable, and discoverable experience with advanced features including the ability to annotate on web pages, a distraction-free reading experience, and integration of Cortana for finding and doing things online faster. It will be single browser that works across devices ranging from smartphones to Surface Hub. One important information is that, it will co-exist with Internet Explorer. Microsoft will have two engines in Spartan, one will be used for rendering modern websites and the other engine for legacy enterprise web sites.
How does it work along with Internet Explorer?
Powered by a new rendering engine, Spartan is designed for interoperability with the modern web. We’ve deliberately moved away from the versioned document modes historically used in Internet Explorer, and now use the same markup as other modern browsers. Spartan’s new rendering engine is designed to work with the way the web is written today.
Like Windows 10 itself Spartan will remain up-to-date: as a service, both providing new platform capabilities, security and performance improvements, and ensuring web developers a consistent platform across Windows 10 devices. Spartan and the new rendering engine are truly evergreen.
Spartan provides compatibility with the millions of existing enterprise web sites designed for Internet Explorer. To achieve this, Spartan loads the IE11 engine for legacy enterprise web sites when needed, while using the new rendering engine for modern web sites. This approach provides both a strong compatibility guarantee for legacy enterprise web sites and a forward looking interoperable web standards promise.
We recognize some enterprises have legacy web sites that use older technologies designed only for Internet Explorer, such as custom ActiveX controls and Browser Helper Objects. For these users, Internet Explorer will also be available on Windows 10. Internet Explorer will use the same dual rendering engines as Spartan, ensuring web developers can consistently target the latest web standards.
