There's not really a "Hobo-specific" way to do this; the standard method would
be to switch to the ActiveRecord session store and have a cron job periodically
sweep out old records. (then you wouldn't need the UserTimeout model)
Alternatively, you could try using a before_filter on your
ApplicationController that checks for the a "last accessed" time in the session
and either boots the user or updates that time. You'd need to hook into the
login method on your user controller:
def login
hobo_login do
session[:last_accessed] = Time.now
end
end
The first method has the advantage that it's possible to scan the sessions
table to see *who* is logged in, whereas the second method can't exactly poke
around in the cookies on the remote machines...
