NAME

CURLOPT_KEEP_SENDING_ON_ERROR - keep sending on early HTTP response >= 300

SYNOPSIS

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

HTTP

EXAMPLE

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

Along with HTTP. Added in 7.51.0.

RETURN VALUE

Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
