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);
         }
       }
