.TH CURLOPT_KEEP_SENDING_ON_ERROR 3 "22 Sep 2016" "libcurl 7.51.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_KEEP_SENDING_ON_ERROR \- keep sending on early HTTP response >= 300
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KEEP_SENDING_ON_ERROR,
                          long keep_sending);
.fi
.SH 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 \fICURLOPT_HTTPAUTH(3)\fP, but instead sets "Authorization: NTLM ..."
headers manually using \fICURLOPT_HTTPHEADER(3)\fP.

Most applications do not need this option.
.SH DEFAULT
0, stop sending on error
.SH PROTOCOLS
HTTP

  curl_easy_setopt(curl, CURLOPT_KEEP_SENDING_ON_ERROR, 1L);
  ret = curl_easy_perform(curl);
}
