You seems telling about locals SharedObjects. Several examples on internet
explains that Shared Objects are used to create chatrooms. My example only
send a message, but i only think to use it to prevent clients to check
"sended messages"... in fact this is what i will do:
- Netconnection to my app
- onSendMessage (send button clicked): call
myApp.sendMessage(username,message)
-> stored on server
-> then send "Message" on remoteSharedObject
- onMessage (sharedobject handler) : call myApp.getMessage()
-> then write on "chat interface"
I only will send basics events message to client. Clients will call
Application method to get messages.
The real benefits to use SharedObject here is to be easilly synchronized
with clients... Am i really wrong ?
