CURLOPT_KEEP_SENDING_ON_ERROR(3) Library Functions Manual
NAME
CURLOPT_KEEP_SENDING_ON_ERROR - keep sending on early HTTP response >=
300
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KEEP_SENDING_ON_ERROR,
long keep_sending);
DESCRIPTION
A long parameter set to 1 tells the library to keep sending the request
body if the HTTP code returned is equal to or larger than 300. The
default action would be to stop sending and close the stream or
connection.
This option is suitable for manual NTLM authentication, i.e. if an
application does not use CURLOPT_HTTPAUTH(3), but instead sets
"Authorization: NTLM ..." headers manually using CURLOPT_HTTPHEADER(3).
Most applications do not need this option.
DEFAULT
0, stop sending on error
PROTOCOLS
This functionality affects http only
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode ret;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "sending data");
curl_easy_setopt(curl, CURLOPT_KEEP_SENDING_ON_ERROR, 1L);
ret = curl_easy_perform(curl);
}
}
AVAILABILITY
