Ruby On Rails TCPSocket

Question

I developed a server in C++ and I would like to develop an interface in Ruby On Rails.

So I started to read http://ruby.railstutorial.org/ , meanwhile I start looking if I would be able to create a connection between my Ruby On Rails application and my server.
I find out I could use TCPSocket.

My question is : Could I open just 1 TCPSocket by session (and store it somewhere) ?
Or would I have to open a TCPSocket for every action in my controllers ?

Thanks in advance,

app/models/conn.rb:

class Conn
  @connection = "foo" # Connect here

  def self.get_connection
    @connection
  end
end

Rails console:

irb(main):002:0> Conn.get_connection
=> "foo"

But unless your server is single-threaded you will have more than one connection anyways.
