/*HERE IS THE FIDDLER SCRIPT TO SIMULATE FAULTS
Open Fiddler. 
Go to Rules > Customize Rules.
Find the OnBeforeResponse method. Add the commented-out code given below.
Be sure the hostname is [yourstorageaccount].blob.core.windows.net. 
Start the app, then pause it after it's working and 
uncomment the if clause to intercept the response and return a 503 error to the client application.
The script change must be commented out when you first run the application.
