Figure 2-82 Flow of service component invocation request or response using HTTP adapter

During service component invocation request, the request message passed from the business process is sent to the service component transformed to HTTP request in HTTP adapter. During response, HTTP response sent from the service component is transformed to a response message in HTTP adapter and passed to the business process.

HTTP adapter supports session maintenance using Cookie and file upload and download functions. You can also send files uploaded from HTTP client to the server and files downloaded from the server to HTTP client by using HTTP adapter combined with HTTP reception.
