History
ColdFusion MX 6.1: Added the ability to dump COM objects; it displays the methods and Get and Put properties typeinfo information for the object.
Usage
The expand/contract display capability is useful when working with large structures, such as XML document objects, structures, and arrays.
To display a construct, use code such as the following, in which myDoc is a variable of type XmlDocument:
    <cfif IsXmlDoc(mydoc) is "True">
       <cfdump var="#mydoc#">
    </cfif>
The tag output is color-coded according to data type.
If a table cell is empty, this tag displays "[empty string]".
Example This example shows how to use this tag to display a URL variable. URL variables contain parameters that are passed in a URL string in a page request.
    <cfdump var="#URL#">
