.SH DESCRIPTION
|
|
|
|
|
A long parameter set to 1 tells the library to fail the request if the HTTP
|
|
|
|
|
code returned is equal to or larger than 400. The default action would be to
|
|
|
|
|
return the page normally, ignoring that code.
|
|
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
|
|
|
|
|
You might get some amounts of headers transferred before this situation is
|
|
|
|
|
detected, like when a "100\-continue" is received as a response to a POST/PUT
|
|
|
|
|
and a 401 or 407 is received immediately afterwards.
|
|
|
|
|
|
|
|
|
|
When this option is used and an error is detected, it causes the connection to
|
|
|
|
|
get closed and \fICURLE_HTTP_RETURNED_ERROR\fP is returned.
|
|
|
|
|
.SH DEFAULT
|
|
|
|
|
0, do not fail on error
