The sample code demonstrates a way to serve files from storage via a web role. A file from blob storage (such as http://xxx.cloudapp.net/files/File1) can be reached as the normal files in your application by relative path ("files/File1"). And this http module can also filter some specify types files. There is a HttpModule runs before every http request to check the types of requested files and get it from blob storage, and it can also check if the file exists.
You can find more code samples that demonstrate the most typical programming scenarios by using Microsoft All-In-One Code Framework Sample Browser or Sample Browser Visual Studio extension. They give you the flexibility to search samples, download samples on demand, manage the downloaded samples in a centralized place, and automatically be notified about sample updates. If it is the first time that you hear about Microsoft All-In-One Code Framework, please watch the introduction video on Microsoft Showcase, or read the introduction on our homepage http://1code.codeplex.com/.
