Use the Headers VIs to manage header field lines for Web requests associated with client handles. These VIs also can interact with LabVIEW Web services.

AddHeader VI
Adds a header field line to all Web requests associated with the client handle. Headers define attributes of the data exchanged between the client and server.
RemoveHeader VI
Removes a header field line from all Web requests associated with the client handle. Headers define attributes of the data exchanged between the client and server. Client handles save header values across multiple Web requests. Use the Open Handle VI to create a client handle. Refer to the World Wide Web Consortium website at www.w3.org for more information about header field definitions including example headers, descriptions, and syntax.
GetHeader VI
Returns the value assigned to the header of the client handle. Headers define attributes of the data exchanged between the client and server. Client handles save header values across multiple Web requests. Use the Open Handle VI to create a client handle. Refer to the World Wide Web Consortium website at www.w3.org for more information about header field definitions including example headers, descriptions, and syntax.
HeaderExists VI
Determines if the header is associated with the client handle. Headers define attributes of the data exchanged between the client and server. Client handles save header values across multiple Web requests. Use the Open Handle VI to create a client handle. Refer to the World Wide Web Consortium website at www.w3.org for more information about header field definitions including example headers, descriptions, and syntax.
ListHeaders VI
Lists the headers associated with the client handle. Headers define attributes of the data exchanged between the client and server. Client handles save header values across multiple Web requests. Use the Open Handle VI to create a client handle. Refer to the World Wide Web Consortium website at www.w3.org for more information about header field definitions including example headers, descriptions, and syntax.
