Help with server side best practices

[Winston Nimchan]

Hi:

I am trying to develop a server application that listens for incoming
network request and processes these requests. Processing request involves
analyzing the packet, applying business rules, updating database and
generating a response packet.

What is the best way to go about this?

I've downloaded code from the net that creates an asynchronous socket server
but I have some concerns about what I'm doing. Threads are created for each
incoming socket and when data is received on a particular socket, the
delegate is called. the problem is that if a second socket/thread receives
data while the first socket/thread is in the delegate, the second thread
waits for the first thread to exit the delegate. It might be a while before
the first thread finishes.

Is it wise to make async calls from my delegate to the objects that will be
processing the request?

Forgive me if I sound confused.

Regards

Winston

Is it necessary to write your own application server? If this is a business
application, you could be using IIS and ASP.NET web apps or web services.

Thankx for your suggestion

Basically this is what I want to achieve...
A POS terminal captures data and formats according to ISO8583 protocol
Connects to my host via tcpip and sends the request
My host decodes the request, processes it and generates a response to the
terminal

What do you think is the best, quickest way to achieve this
