Metasploit Server Module

[phalse]

Hey all, I am trying to develop a metasploit module that acts as a server.  I need the module to accept a request, send a payload, accept a second request, and send a second response.  The problem that I am running into is all of the modules I am finding just do 1 exchange in a fire-and-forget format.

My current code takes every request as a separate connection and closes after 1 exchange.  Any idea how I can accomplish this?

 

Here is what I have so far:
 

class MetasploitModule < Msf::Exploit::Remote
  Rank = NormalRanking

  include Msf::Exploit::Remote::HttpServer
  def initialize(info = {})
    super(
      update_info(
        info,
        'Name'           => 'Test',
        'Description'    => %q(
            test desc.
        ),
        'License'        => MSF_LICENSE,
        'Author'         => ['me'],
        'Targets'        =>
          [
            [
              'Linux',
              {
                'Platform' => 'linux'
              }
            ],
          ]
      )
    )
    register_options([
        OptString.new('SRVHOST', [false, 'The local host to listen on.  This must be an address on the local machine or 0.0.0.0', '0.0.0.0']),
        OptString.new('SRVPORT', [false, 'The local port to listen on', '80']),
        OptString.new('URIPATH', [false, 'The URI to use', 'test_file']),
    deregister_options('SSL', 'SSLCert')
  end

  def on_request_uri(cli, request)
    if some_condition
      response = create_response(200)
      cli.send_response(response)
    else
      response = create_response(404)
      cli.send_response(response)
    end
  end
