Microsoft's Web Sandbox is now open source
Microsoft's Web Sandbox Live Labs project is now available under an open source license. Microsoft chose the Apache 2.0 license for the project, but pointed out that the project will not become an Apache project, although the vendor has been a member of the Apache Software Foundation since July 2008.
The Sandbox technology aims at allowing developers to create secure mash-up solutions and page extensions, like ads, or web-based gadgets, by isolating the components. In addition, the project wants to provide interoperability with script frameworks.
The software giant presented Web Sandbox in a Community Technology Preview (CTP) at its Professional Developers Conference (PDC) in autumn 2008, but the project was slightly overlooked, as the media largely responded to other technologies, like Windows 7 and Azure. The project is based on Microsoft's experience with DHTML, web-based gadgets and the BrowserShield project.
