Parameters
Parameter |
Description |
|---|---|
namespace |
A string that is the namespace for the header. |
name |
A string that contains the name of the SOAP header in the request. |
value |
The value for the SOAP header; this can be a CFML XML value. |
mustunderstand |
Optional. True or False (default). Sets the SOAP mustunderstand value for this header. |
Usage
Call this function only from within a CFC web service function. It throws an error if it is invoked in a context that is not a web service request.If you pass XML in the value parameter, ColdFusion ignores the namespace and name parameters. If you require a namespace, define it within the XML itself.Use the IsSOAPRequest function to determine if the CFC is running as a web service.
Example
This example creates a CFC web service that illustrates the operation of the AddSOAPResponseHeader function and also provides a web service that illustrates the operation of other ColdFusion SOAP functions. Save the following code as headerservice.cfc in a folder called soapheaders under your web root. Test its operation, and specifically the operation of the AddSOAPResponseHeader function, by executing the examples that invoke this web service. For example, see the example for AddSOAPRequestHeader.
