Accelerating Traffic with Intelligent Client Cache

Intelligent Client Cache (ICC) is a web acceleration technique for mobile and desktop browsers that support HTML5. ICC uses HTML5 local storage to build a cache of documents and resources. It does this either by replacing the link to CSS/JavaScript/Image by inlining them into the HTML document, or by replacing the link to CSS/JavaScript/Image by adding reference to content that might already be in the client's local storage. Local storage is a simple key-value storage in HTML5 and is shared across all browser windows and tabs. Most common implementations allow 5-10 MB per domain. Client-side JavaScript code tracks the resources cached and interacts with the server-side code to ensure that only changed resources are downloaded on subsequent requests.

Browsers that support web storage:

• Internet Explorer version 8+
• FireFox version 3.6+
• Opera 10.5+
• Chrome 5+
• Safari 4+
• iOS 3.2+
• Android 2.1+
