[Version 5.0.2 and later]Transports

A transport is the request queue between a WebSphere Application Server plug-in for Web servers and a Web container in which the Web modules of an application reside. When a user at a Web browser requests an application, the request is passed to the Web server, then along the transport to the Web container.

Transports define the characteristics of the connections between a Web server and an application server, across which requests for applications are routed. Specifically, they define the connection between the Web server plug-in and the Web container of the application server.

Administering transports is closely related to administering WebSphere Application Server plug-ins for Web servers. Indeed, without a plug-in configuration, a transport configuration is of little use.

The internal transport

The internal HTTP transport allows HTTP requests to be routed to the application server directly through a Web server plug-in. Logging is provided for debug purposes.

Prior to WebSphere Application Server Version 5.0.2, the HTTP transport functionality existed only as a means of accepting HTTP requests forwarded by an HTTP plug-in that was connected to a Web server. In Version 5.0.2, HTTP transport functionality is now a supported internal Web server. By default, the internal HTTP transport listens for HTTP requests on port 9080 and for HTTPS requests on port 9443.

For example, use the URL http://localhost:9080/snoop to send requests to the snoop servlet on the local machine over HTTP and https://localhost:9443/snoop to send requests to the snoop servlet on the local machine over HTTPS.

The transport configuration is a part of the Web container configuration. You can configure the internal transport to use ports other than 9080 and 9443, . However, you must also adjust your virtual host alias and what you type into the Web browser.
