We Need a Viewport Header

Responsive design techniques are the future for the web, and for good reason. The ever-increasing number and variety of devices and their screen sizes makes the practice of dedicated desktop and mobile sites not only outdated, but unscalable. I’m a huge proponent of responsive & adaptive design and implement these technologies in every site I build. Despite all the amazing benefits they provide, there’s still something that bugs me as a developer: lack of server-side responsiveness.
