CURLOPT_K...G_ON_ERROR(3)  Library Functions Manual  CURLOPT_K...G_ON_ERROR(3)

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  de-
       fault  action  would be to stop sending and close the stream or connec-
       tion.

       This option is suitable for manual NTLM authentication, i.e. if an  ap-
       plication  does	not  use CURLOPT_HTTPAUTH(3), but instead sets "Autho-
       rization: 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
       Added in	curl 7.51.0

RETURN VALUE
       curl_easy_setopt(3) returns a CURLcode indicating success or error.

       CURLE_OK	(0) means everything was OK, non-zero means an error occurred,
       see libcurl-errors(3).
