bool Security::CreateClientSession ( const Security::ContextPointer ctx,
const Comm::ConnectionPointer c,
const char *  squidCtx 

Creates TLS Client connection structure (aka 'session' state) and initializes TLS/SSL I/O (Comm and BIO). On errors, emits DBG_IMPORTANT with details and returns false.

Security::ContextPointer Security::GetFrom ( Security::SessionPointer s)
void Security::MaybeGetSessionResumeData ( const Security::SessionPointer s,
Security::SessionStatePointer data 

When the session is not a resumed session, retrieve the details needed to resume a later connection and store them in 'data'. This may result in 'data' becoming a nil Pointer if no details exist or an error occurs.

When the session is already a resumed session, do nothing and leave 'data' unhanged. XXX: is this latter behaviour always correct?
