ColdFusion MX 6.1: Web Service Headers with ColdFusion MX
There is currently no mechanism in Macromedia ColdFusion MX 6.1 to create or process header fields in web services. This TechNote provides a patch to Apache Axis to allow users to retrieve the response headers from a web service request, as well as a hot fix to allow users to create a SOAP header in a request that has the "mustUnderstand" attribute set to be true.
