The following example creates an array named headers that contains two alternating HTTP
headers and their associated values. The array is passed as a parameter to the
addRequestHeader() method.
var headers:Array = new Array("Content-Type", "text/plain", "X-
ClientAppVersion", "2.0");
my_xml.addRequestHeader(headers);

Example
The following example creates a new XML document and checks its default content type:
// create a new XML document
var doc:XML = new XML();
// trace the default content type
trace(doc.contentType); // output: application/x-www-form-urlencoded
The following example defines an XML packet, and sets the content type for the XML object.
The data is then sent to a server and shows a result in a browser window.
var my_xml:XML = new XML("Ernie13045");
my_xml.contentType = "text/xml";
my_xml.send("http://www.flash-mx.com/mm/highscore.cfm", "_blank");
