qUIpt: caching JS in window.name

Mario Heiderich has released qUIpt, a library that uses the window.name property to store away useful data, in this case JavaScript.

How does it work?

• It checks for the contents of window.name while your page is being loaded.
• If there’s nothing inside the window.name cache the JS files defined by you are fetched via XHR
• The same happens if the users enters your site for the first time of his current browser session or if document.referrer is off-domain or empty
• After that the contents of window.name are being evaluated
• If the user requests the next page on your domain the JS files are directly taken from window.name – no more requests necessary
