Listeners

A listener object contains a network address that accepts incoming client requests on behalf of services. A service can have multiple listeners, and a listener can accept client requests on behalf of multiple services.

You can configure a listener to use SSL (Secure Sockets Layer) - a facility for secure, encrypted communication and checking online identities.

Each listener is associated with a connector. This is software that can process the type of requests the listener handles.

Enterprise Server comes with several connectors, including:

• The soap connector, which handles both Web Services SOAP requests and the Micro Focus Binary Protocol used for J2EE requests.
• The http-switch connector, which provides simple web server capabilities and is used for service deployment.
• The http-echo connector, which responds to HTTP requests with a short HTML reply and can be used for connection testing.
  Note: Do not use the http-echo conversation type in production. It is intended only for connection testing. Older versions of the http-echo module are vulnerable to web cross-site scripting (XSS) attacks, which are a serious security exposure.
