问题
How can I test that a web app successfully falls back from one faulty back-end API to a secondary legacy API service?
Could Firebug or Chrome, or Fiddler do it?
How can I setup my client to return error responses for ajax calls to a certain URL pattern?
- Using HTTPS.
- I don't have control over the server-side.
- I want to err just certain ajax calls the remaining should work the same (pulling the network plug is not an option).

Yes, Fiddler can do this easily. In Fiddler, click the AutoResponder tab. Create a new rule that specifies the behavior you want. For instance:
If request matches: webdbg.com/test/Service1
Then respond with: *drop
If Fiddler ever gets a request for the specified URL, it will immediately close the connection. Or you could set the response action to return a HTTP/5xx error, or use *reset to TCP/IP RESET the connection.
