Fail silently (no output at all) on server errors. This is mostly done to
|

|
|
|
enable scripts etc 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).
