Abstract
A message processor accesses an electronic message. The accessing message processor identifies, from within the electronic message, any communication session information associated with the accessing message processor. This can include identifying expressive XML instructions or XML data structures representing communication sessions or message sequences. The accessing message processor determines if any session information within the electronic message is to be modified. This can include inserting session information for new sessions or message sequences, updating existing session information, or removing session information for terminated or expired communication sessions or message sequences. The accessing message processor then routes the electronic message to another message processor. In some embodiments, an initiating message processor identifies cached session information that is used to initially establish a communication session. The identified session information is included in a session element that is routed to one or more receiving message processors.
