The HTTP/2 Server agent enables you to configure an HTTP server in a real-time workflow. The agent receives requests, converts them into UDRs routed into the workflow, and then sends responses back over a TCP/IP connection.

| |||||
| Status Code | The HTTP error code for the error response. The default error code set is 503 for server shutdown and 429 for server overload. | |||||
| Content Type | ||||||
| UDR Type | Browse for the UDR that will be populated as part of the HTTP response message. | |||||
