Chat doesn't follow user to different computer

A new install of openfire and spark in an environment where some users move from desk to desk depending on the day. We are finding that when a user moves to another computer, their previous chats are gone. Is there a solution to this?

Spark doesn’t support server history. Everything is stored locally on a computer. On Windows it is in C:\Users\User\AppData\Roaming\Spark (among with other settings). Solution depends on technologies you use or know. Maybe you can copy this folder to some server storage periodically and when user logs in into computer copy it from the server. This is just one idea.
