Browser cache is one of the anchor tenants of web optimization, and has been around since the early days of the web. Unfortunately, such veteran optimizations often don’t keep up with the times. The last real improvement to browser caching happened in 1999, when the cache-control header was added in HTTP 1.1. One of the many changes in the web since then is the use of JavaScript, moving from rare and minor usage in 1999 to being a dominant technology in web pages today.

During our constant research of optimization techniques at Blaze, we repeatedly uncovered great optimization techniques that could be implemented if only scripts had access to the cache. Eventually, since browsers don’t provide this capability, we decided to write it ourselves. Leveraging HTML5 localStorage, we wrote a script-based caching system, and started building optimizations on top of it.

Here are some of the optimizations our scriptable caching platform enables.**

Everybody agrees the mobile web is big. In the US, Mobile browsing has now surpassed desktop browsing, every 3rd person owns a browsing-enabled phone, and Android devices are selling like hotcakes. With the importance of the Mobile Web comes the importance of Mobile Web Performance, and naturally that spawns a lot of research and conversation.
