utilize either of those methods in your projects.</para>

<para><option>enable-tlsext</option>: When added to the

<command>./config</command> command, this switch will enable TLS

|
Extensions. Currently this is only RFC 3546 and 4507bis for Server Name
|
|
Indication. This allows the use of multiple SSL certificates with multiple

|
virtual hosts in Apache, while using only one IP address and one port for

all virtual hosts.</para>
