What is "html5-history"
HTML5 History API is a custom way to manipulate browser history via script.
Part of this AP - browse the historical - was available in previous versions of HTML.
The new HTML5 parts include a way to add historical entries, to visually change the URL in the browser (without reloading the page), among others.
This means that the URL in the browser’s location bar can continue to make its service as a unique identifier pro resource, even in applications with many scripts that hardly make the page refresh.
