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

       Added in curl 7.51.0

RETURN VALUE

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