Let’s look at the Dojo Offline Toolkit from a user’s perspective. Imagine Alex is using a web-based real estate application for realtors built with the Dojo Offline Toolkit. In the upper-right corner of this web application is a button that says “Work Offline.” The first time Alex clicks on this button, a small window appears informing him that this web application can be accessed and used even if he is offline. If Dojo Offline has never been installed, Alex is prompted to optionally install a small 100K through 300K download that is automatically selected for his appropriate OS, including Windows, Linux/x86, and Mac OS X/Universal Binary.
