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 flag will prevent curl from
|
|
|
|
outputting that and return error 22.

This method is not fail-safe and there are occasions where non-successful
|
|
|
|
response codes will slip through, especially when authentication is involved
|
|
|
|
(response codes 401 and 407).
