Fail fast with no output at all on server errors. This is useful to enable scripts and users to better deal with failed attempts. In normal cases when an HTTP server fails to deliver a document, it returns an HTML document stating so (which often also describes why and more). This command line option prevents curl from outputting that and return error 22.
This method is not fail-safe and there are occasions where non-successful response codes slip through, especially when authentication is involved (response codes 401 and 407).
