What's qUIpt?
qUIpt is a small library that is capable of caching Javascript files inside the users browser - even if SSL is active. qUIpt helps the site owner by reducing traffic costs and the user with faster page loading. Developers by the way might want to check https://groups.google.com/group/quipt
How does it work?
- Quite simple
- 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
Is this secure?
- Yep - if the user enters your site the first time the JS files are requested - no matter what's already inside window.name
- An attacker can't set window.name from other tabs the user might surf on parallely
Click for happiness
Feedback is always appreciated - especially in this very early stage of the project.
