+.TH CURLOPT_SSL_FALSESTART 3 "14 Feb 2015" "libcurl 7.41.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_SSL_FALSESTART \- enable TLS false start
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_FALSESTART, long enable);
+.SH DESCRIPTION
+Pass a long as parameter set to 1 to enable or 0 to disable.
+
+This option determines whether libcurl should use false start during the TLS
+handshake. False start is a mode where a TLS client will start sending
+application data before verifying the server's Finished message, thus saving a
+round trip when performing a full handshake.
+.SH DEFAULT
+0
+.SH PROTOCOLS
+All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc.
+.SH EXAMPLE
+TODO
+.SH AVAILABILITY
+Added in 7.42.0. This option is currently only supported by the NSS TLS
+backend.
+.SH RETURN VALUE
+Returns CURLE_OK if false start is supported by the SSL backend, otherwise
+returns CURLE_NOT_BUILT_IN.
