Configure SSLv2 redirection
To initiate an SSL transaction and for successful completion of the SSL handshake, the server and the client must agree on an SSL protocol that both support. If the SSL protocol version supported by the client is not acceptable to the server, the server does not go ahead with the transaction. An error message is displayed.
You can configure the server to display a precise error message (user-configured or internally generated) advising the client on the next action to be taken. Configuring the server to display this message requires that you set up SSLv2 redirection.
