	LabVIEW Web Service Request is an identifier used by Web Services VIs to reference a specific HTTP request. LabVIEW Web Service Request works similarly to a refnum in LabVIEW, allowing you to wire together Web Services VIs within your application. You must wire Web Services VIs to the LabVIEW Web Service Request control or an existing value from the LabVIEW Web Service Request out terminal of another VI. When you use Web Services VI(s) within a Web method VI, you must assign the original LabVIEW Web Service Request control to the connector pane of the Web method VI.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	LabVIEW Web Service Request out is an identifier that VIs on the Web Services palette use to reference a specific HTTP request. Use LabVIEW Web Service Request out to wire together Web Services VIs within your application.
