+Help: Fail silently (no output at all) on HTTP errors
+---
+Fail silently (no output at all) on server errors. This is mostly done to
+better 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).
