Scenario: Configuring HTTP tunneling

In this scenario, we can test a simple connection between two instances of MQIPT over HTTP.

Before you begin

Before you start to use this scenario, make sure that we have completed the prerequisite tasks listed in Scenarios: Getting started with MQIPT.

About this task

This diagram shows the connection from the IBM MQ client (called client1.company1.com on port 1415) through two instances of MQIPT, tunnelling the connection over HTTP, and finally to the IBM MQ server (called server1.company2.com on port 1414).

Procedure

To configure an HTTP proxy, complete the following steps:

1. On MQIPT1:
   1. Edit mqipt.conf and add a route definition:

      [route]
      ListenerPort=1415
      Destination=10.100.6.7
      DestinationPort=8080
      HTTP=true
      HTTPServer=10.100.6.7
      HTTPServerPort=8080
      

   2. Open a command prompt and start MQIPT:

      C:\mqipt\bin\mqipt C:\mqiptHome

      where C:\mqiptHome indicates the location of the MQIPT configuration file, mqipt.conf. The following message indicates successful completion:

      MQCPI066 ....and HTTP server at 10.100.6.7(8080)

2. On MQIPT2:
   1. Edit mqipt.conf and add a route definition:

      [route]
      ListenerPort=8080
      Destination=Server1.company2.com
      DestinationPort=1414

   2. Open a command prompt and start MQIPT:

      C:\mqipt\bin\mqipt C:\mqiptHome

      where C:\mqiptHome indicates the location of the MQIPT configuration file, mqipt.conf. The following message indicates successful completion:

      5639-L92 (C) Copyright IBM Corp. 2000, 2017 All Rights Reserved

      MQCPI011 The path C:\mqiptHome\logs will be used to store the log files

      MQCPI035 ....using MQ protocols
      MQCPI078 Route 8080 ready for connection requests
      

3. At a command prompt on the IBM MQ client, enter the following commands:
   1. Set the MQSERVER environment variable:

      SET MQSERVER=MQIPT.CONN.CHANNEL/tcp/10.9.1.2(1415)

   2. Put a message:

      amqsputc MQIPT.LOCAL.QUEUE MQIPT.QM1
      Hello world

      Press Enter twice after typing the message string.
   3. Get the message:

      amqsgetc MQIPT.LOCAL.QUEUE MQIPT.QM1

      The message, "Hello world" is returned.
