Configure an intermediary node for web services transactions

Intermediary nodes allow the exchange of Web Services Atomic Transaction (WS-AT) and Web Services Business Activity (WS-BA) protocol messages across firewalls and outside the WebSphere Application Server domain. You configure an intermediary node to specify which WebSphere Application servers the node routes requests to.

1. Configure the HTTP server so that it routes WS-AT and WS-BA requests that are targeted at WAS to WAS, rather than processing them itself.

• Example: Configuring IBM HTTP server as an intermediary node for web services transactions
  We can use an HTTP server intermediary nodes to enable the exchange of Web Services Atomic Transaction and Web Services Business Activity protocol messages across firewalls and outside the WAS domain. For IBM HTTP server, you achieve this behavior by modifying the plugin-cfg.xml file of the IBM HTTP server node.
