Have you ever noticed that when you're browsing Facebook and click on a link, like a friend's profile or the home button, the entire page refreshes except for the chat?
Is there a way to instruct the browser to reload the page without refreshing a specific part of it?
For further information, take a look at this resource. In essence, HTML5 brought in a functionality (history.pushState(), history.replaceState() and window.onpopstate) that enables you to alter the URL shown in the browser's address bar without triggering a page reload.
It appears that Facebook uses different techniques depending on the browser:
history.pushState (tested on current versions of Chrome and Firefox)facebook.com/events to facebook.com/?sfrm=1#!/events/ (or something similar).One possible solution might involve utilizing AJAX functionalities or implementing a setup similar to the following:
<body>
<iframe src="content.php" id="content_frame">
<p>Your browser doesn't support iframes.</p>
</iframe>
<iframe src="chat.php" id="chat_frame">
<p>Your browser doesn't support iframes.</p>
</iframe>
</body>
