Whether to use SNI (Server Name Indication) when walking with
SSL/HTTPS. SNI enables a single-IP HTTPS server to serve the correct
certificate when serving multiple hosts, and is thus required by many
multi-homed name-based virtual host HTTPS servers. Disabling SNI may
be useful in some circumstances to connect to
long-handshake-intolerant HTTPS servers that otherwise timeout, by
reducing the size of the SSL ClientHello message. Default is
Y. Shortening the cipher list via SSL Client Ciphers
(here) is another way to work around
long-handshake-intolerant servers.
