%X In the occam\-π programming language, the
   client\-server communication pattern is generally
   implemented using a pair of unidirectional channels. While
   each channel\[rs]s protocol can be specified individually,
   no mechanism is yet provided to indicate the relationship
   between the two protocols; it is therefore not possible to
   statically check the safety of client\-server
   communications. This paper proposes two\-way protocols for
   individual channels, which would both define the structure
   of messages and allow the patterns of communication between
   processes to be specified.We show how conformance to
   two\-way protocols can be statically checked by
   the occam\-π compiler using Honda\[rs]s session
   types. These mechanisms would considerably simplify the
   implementation of complex, dynamic client\-server systems.
