CURLOPT_SASL_IR(3) Library Functions Manual CURLOPT_SASL_IR(3)
NAME
CURLOPT_SASL_IR - send initial response in first packet
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_IR, long enable);
DESCRIPTION
Pass a long. If the value is 1, curl sends the initial response to the
server in the first authentication packet in order to reduce the number
of ping pong requests. Only applicable to the following supporting SASL
authentication mechanisms:
* Login * Plain * GSSAPI * NTLM * OAuth 2.0
Note: Whilst IMAP supports this option there is no need to explicitly
set it, as libcurl can determine the feature itself when the server
supports the SASL-IR CAPABILITY.
DEFAULT
0
PROTOCOLS
IMAP and SMTP
