This question was posted in response to the following article: http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-6c a1.html
I believe the explanation regarding asXML is incorrect.
If true, the header is returned as ColdFusion XML document object. Correct!
However, the funny thing that we still need to parse using xmlParse() to get values. Why?
If false, the header is returned as a Java object. Wrong!
The header is returned as a plain text/string.
