TCP client and multithreaded server in 14 lines of Ruby code

Server:

require "socket"
server = TCPServer.open(2626)
loop do
	Thread.fork(server.accept) do |client| 
 client.puts("Hello, I'm Ruby TCP server", "I'm disconnecting, bye :*")

To be able to program in ColdFusion, a ColdFusion server needs to be installed. There are a couple of options available, but the one that we are going to focus on is a local development server.

A local development server is free and allows you to develop ColdFusion applications that use all of ColdFusion’s available features. There are, however, a few limitations, such as not being able to use the server as an external web server. That being said, there are additional benefits to using a local ColdFusion development server, such as not needing to have IIS or Apache installed, but instead using the packaged web server.

To install ColdFusion, follow the steps below:
