Using HTTP Request IDs
Nearly all of the VIs on the Web Services palette
require an HTTP request ID to identify a specific HTTP request. The HTTP request
ID works similarly to a refnum in LabVIEW, allowing you to wire VIs from the
Web Services palette within your application using a unique
identifier for the current HTTP request. To access an HTTP request ID, create a
32-bit unsigned integer control with the label httpRequestID and wire the control to the connector pane
of a Web Service VI.
