javascript - Preloading of html web page or non-flash web applications? -


I believe most of you have heard about loading images.

But someone who knows, for example, when we are logged into Gmail, we will see a loading progress bar.

What is the HTML webpage / web application (non-flash based) doing Gmail?

The best regards

The stateless nature of the HTTP protocol, Pre-loading webpage can be challenging One way to achieve this is to initially send at least the HTML to the client and then increase the parts of the site progressively. During those times, those AJAX requests are being executed, you can say some spinners on the page that the site is being loaded, but if you want real progress bars (like a Gmail usage) then things even more Become challenging
