+.SH NAME
+CURLOPT_KEEP_SENDING_ON_ERROR \- keep sending on early HTTP response >= 300
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KEEP_SENDING_ON_ERROR, long keep_sending);
+.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
+.SH EXAMPLE
+TODO
+.SH AVAILABILITY
+Along with HTTP
+.SH RETURN VALUE
+Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
+.SH "SEE ALSO"
