| 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). |
