This patch does'nt add any new feature: the functional behavior is the same than version 1.0. Technical differences: In this version all updates on different stick tables are multiplexed on the same tcp session. There is only one established tcp session per peer whereas in first version there was one established tcp session per peer and per stick table. Messages format was reviewed to be more evolutive and to support further types of data exchange such as SSL sessions or other sticktable's data types (currently only the sticktable's server id is supported).
