readable non-transient computer medium; Method for providing an external device with a session in a distributed computer environment and System for providing an external device with a session in a distributed computer environment A system and method implemented in computer are disclosed to provide a user with a consistent user session view in a distributed environment, where session requires establishing conversations between the external device (200,300,300 ') and application servers (a1, ..., c4) of a system (100). system 100 is provided with at least one forwarding means 10,15 configured to establish, for a given session, a conversation between the external device 200,300,300 'and one of the application servers. Establishing the conversation comprises the following steps performed in the routing means (10,15) with at least one data processor: sym receiving a call from one between the application server and the external device to reach the other between the application server and external device; sym determine if the call comprises a session identifier (id), - if the call does not comprise a session id that uniquely identifies that session, add the session id to the call, store the session id and forward the call to each other between the application server and the external device (200, 300, 300 '), thereby establishing the conversation; - if the call already comprises a session id, then forward the call to the other between the application server and the external device (200,300,300 ') and allow said conversation to join an already open session that is uniquely identified by said session id, thereby establishing the conversation and enabling the conversation to share the context of said already opened session.
