I need your help to solve next issue: I am developing MVC application and want to send instant messages between users. This message will ne standard - it's like notification. I am thinking about two optins:
use XMPP protocot, but I don't need the huge amount of options it could provide, I need just basic functionality I've discribed;
have some static array in MVC application with users invitations were send to and ajax function which will call controller action, check if user is in static list. If yes - make message visible on the page. And plus do page autoupdate. But I am not sure about this becouse array will be called very often.
What do you think, guys? Do you have any ideas? I will be very thankfull for any help!
