FMS block port detection – ActionScript 3
The fms port (1935) closed on many office firewalls, the problem
is that flash had 30 sec timeout before tunnle it to port 80.
Becouse that i write little script that use socket object to test the
port and tunnle it to http when port 1935 is closed.

jQuery Communicator Singleton (Manage & Cache ajax requests)
Hey,
I wrote this class for cache ajax request if the same request sent twice.
The second reason why i use this class is a like there is only one exit point
from the application.
