Hi,

At the moment a poker-network REST server imposes a constraint to the
client : when a user is logged in it can only open a single session.
It makes sense for when a user plays at a poker table. When the user
polls the server, the packets that describe the actions done since the
last poll must be sent.

What we would like is to be able to open as many sessions as the user
wants. The only problem I see at the moment is that for a poker table
there can only be one session for the user to play. There can be
multiple observers, but the logged in user cannot have two sessions
acting on behalf of the same user on a table. That could be the case,
for instance, if a jpoker session co-exists with a pok.me session. Or
if two tabs on the same navigator are open on the same table.

At the moment the latest session wins and all other sessions are
terminated. It is maybe enough, for a first step, to limit this
restriction to a player sit at the table. It is better explained with
an example, I'm not being very clear ;-)

At present:

Tab One : TableSelect ( countfilter = 1 ) : ok
Tab Two : TableJoin ( countfilter = 2 ) : ok
Tab One : TableSelect ( countfilter = 1 ) => disconnected by the
countfilter restriction server side
Tab Two : Seat ( countfilter = 2) : ok

The above is useless but if the two tabs do TableJoin, only one will
get the packets describing the table action instead of each tab
competing to get half of the packets and crash.

What we want:

Tab One : TableSelect : ok
Tab Two : TableJoin : ok
Tab One : TableSelect : ok
Tab Two : Seat : ok

And (probably but not sure):

Tab One : TableJoin game 400 : ok
Tab Two : TableJoin game 400 : ok
Tab One : Seat : ok ( count acting at game 400 : 1 )
Tab Two : Seat : ok ( count acting at game 400 : 2 )
Tab One : Poll for action : count acting at game 400 == but current is
2 : the session becomes an observer session instead of an acting session
Tab Two : Poll for action : ok ( count acting at game 400 : 2 )

The general idea is probably that we keep the limitation of a single
acting session for a given game. But not for all other actions. And
instead of just crashing the client, the acting session becomes a
viewer session.

Comments are welcome. This is a delicate part of the server code and
our goal is probably to minimize the changes and, if possible, find a
simple solution.

Cheers
