Are you talking from a webapp to a server to get updates, or server to

Well in the work I am doing so far I am using tomcat, and the communication
I am referring to is between the flash client and the (tomcat right now)
server.
My question is what type of connection does flash make with the server. Is
it like hitting a web page, or is it like establishing a persistent connection.
I know that AMF is only a servlet, so what I am asking about I guess is the
application server technology that the servlet sits in and flash's
relationship to it.
One of the issues I am concerned about is the way that with flash, you
establish a netconnection then you do your query and then you either do or don't
close it. I presume that opening the connection is establishing a tcp/ip
connection. Does this connection really stay open on the server until you close
the netconnection? If so, how burdensome is it to build and tear down this
connection. It has seemed, at times, slow to me, but I havent done any real
testing.
Also, how much overhead does AMF add to the process. There must be some
fixed overhead, which I need to consider.
I ask these questions because I am building something that will likely have
lots of clients and will need to scale. The wrong decisions now could totally
screw up the architecture.
Thanks
