From f78d9b6bfca13e298c29fadabbbc870b37a0a573 Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Thu, 15 Sep 2011 10:00:23 +0200 Subject: Session class separated into socket-type-specific sessions This is a preliminary patch allowing for socket-type-specific functionality in the I/O thread. For example, message format can be checked asynchronously and misbehaved connections dropped straight away.
