LLPRequestResponse

Use the LLPRequestResponse activity to send a request and receive a synchronous response. The request and response can be in the form of an HL7 string or XML data.

Synchronous response means that the response is sent on the same TCP connection. If a connection is closed, and a response is sent on a different TCP connection, then it is called an asynchronous response.

Note: This activity sends its request to the LLP Receiver activity, which passes the request to the LLP Response activity. If the Is One Way checkbox is not checked, the LLP Request Response activity may get an empty string if the LLP Receiver activity is suspended before the LLP Response activity returns the response to the LLP Receiver.
