I'm using HTTPService (tried with URLLoader but result is the same) to load XML file. Furthermore, XML file is secured with basic HTTP authentication.

There are two kind of events I want to separate:

  • IO Error
  • User refuses to authenticate (pressing cancel on credential request dialog)

The problem is that these two kind of events looks exactly the same (401 Status code is not presented). Is there any way to find out whether IO error occurred or authentication failed?
