Description

With TLS Server Name Indication (SNI), a TLS server can have multiple certificates installed on the same IP address. SNI-capable clients will specify the hostname of the server they’re trying to reach during the initial handshake process. This allows the TLS server to determine the correct certificate to use for the connection.

It would be a useful extension to DCMTK's TLS clients to add a command line enabling SNI. In OpenSSL, this might be as simple as calling the following function:
int SSL_set_tlsext_host_name(const SSL *s, const char *name);
