| |
| .SH NAME |
| CURLOPT_SASL_IR \- enable sending initial response in first packet |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_IR, long enable); |
| .SH DESCRIPTION |
| Pass a long. If the value is 1, curl will send 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 |

| as libcurl can determine the feature itself when the server supports the |
| SASL-IR CAPABILITY. |
