commit 0969c96d8545a40600d6d63b5b9ca54b8c47f76c
Author: Oswald Buddenhagen <[email protected]>
Date: Wed Dec 15 19:01:27 2010 +0100
remove redundant use_ssl variables
just use the presence of an SSL object as an indicator. if something
goes wrong during the ssl handshake or certificate validation, the
socket must be immediately closed anyway.
