Scenario: Configuring an HTTP proxy

In this scenario, we can test the connection using an HTTP proxy (IBM® Caching Proxy).

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.
• Check the following properties in the ibmproxy.conf file:
  • ProxyPersistence must be set to true to permit persistent connections.
  • MaxPersistRequest must be set to 5000, the number of requests allowed on a single connection before the connection is broken.
  • PersistTimeout must be set to 12, the time (in hours) allowed for the connection to exist.
  • Proxy entries must include the USESESSION parameter.

This diagram shows the connection from the IBM MQ client (called client1.company1.com on port 1415) through MQIPT1, through the HTTP proxy computer (on port 1080), through MQIPT2, 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=1416
      HTTP=true
      HTTPProxyPort=8080
      HTTPProxy=10.9.6.7

   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:

      MQCPI024 ....and HTTP proxy at 10.9.6.7(8080)

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

      [route]
      ListenerPort=1416
      Destination=Server1.company2.com
      DestinationPort=1414

   2. Open a command prompt and start MQIPT:

      C:
      cd \mqipt\bin
      mqipt ..

      where .. indicates that the MQIPT configuration file, mqipt.conf, is in the parent directory.The following message indicates successful completion:

      MQCPI035 ....using MQ protocols
      MQCPI078 Route 1416 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.
