addRequestHeader (XML.addRequestHeader method)

public addRequestHeader(header:Object, headerValue:String) : Void

Adds or changes HTTP request headers (such as Content-Type or SOAPAction) sent with POST actions. In the first usage, you pass two strings (header and headerValue) to the method. In the second usage, you pass an array of strings, alternating header names and header values.

If multiple calls are made to set the same header name, each successive value replaces the value set in the previous call.

You cannot add or change the following standard HTTP headers using this method: Accept-Ranges, Age, Allow, Allowed, Connection, Content-Length, Content-Location, Content-Range, ETag, Host, Last-Modified, Locations, Max-Forwards, Proxy-Authenticate, Proxy-Authorization, Public, Range, Retry-After, Server, TE, Trailer, Transfer-Encoding, Upgrade, URI, Vary, Via, Warning, and WWW-Authenticate.

header:Object - A string that represents an HTTP request header name.

headerValue:String - A string that represents the value associated with header.


The following example adds a custom HTTP header named SOAPAction with a value of Foo to an XML object named my_xml:

my_xml.addRequestHeader("SOAPAction", "'Foo'");

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");
