  					W3C Sample Code Library libwww SSL Transport Wrapper


!
  SSL Transport Wrapper
!

This module declares a SSL (using the OpenSSL
library) transport wrapper so that libwww can use SSL as a
transport the same way it can use TCP and
local host as transports. This module keeps a context of the application
(SSL_CTX), Cipher negotiation, certificate directory path setting
could be added here.

The module is contributed by Olga Antropova
