Curious about the new way YouTube is loading pages -


i've noticed when i'm watching video , click on logo or related video red progress bar (above logo) dashes across screen. @ same time there slight overlay "grey" out content fades in new page. fyi, url changes new url before progress bar , transition happens.

the div id of bar progress. looks kind of cool jquery ajax load changing pages. don't know.

enter image description here

youtube using html5 history api add , remove page urls history stack. results in url changing in address bar, , back/forward buttons working, while still loading page via js (ajax).

the easiest way implement api backwards compatibility @ point using history.js. backwards compatibility mean falling hash tag method older browsers not support html5 history api yet.

check out history.js demo!

i think twitter best known example of website using hashed urls. example twitter.com/#!/username has been common sight years. problem method hash tags client side, need js read them , serve proper content. non-js user clicking hashed url land on twitter's homepage.

beatport 1 of first major websites using html5 history technique way. soundcloud has implemented too. both sites needed html5 history badly, ensure audio playback while visitors browse through pages.
