feature: history status: use tags: fallback kind: api polyfillurls:
The History API provides a way for JavaScript to change the URL displayed in the browser without reloading the page. There are several approaches to providing a fallback. The simplest is to fall back to page refreshes. Alternatively, the History.js plugin smooths out some browser implementation differences and provides an optional hashchange fallback for HTML 4 browsers. GitHub uses pjax (pushState + ajax).
