LoadVars 393
Adds or changes HTTP request headers (such as
Content-Type
or
SOAPAction
) sent with
POST
actions. In the first usage, you pass two strings to the method:
header
and

. 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 will replace the
value set in the previous call.
The following standard HTTP headers cannot be added or changed with this method:

Example
The following example adds a custom HTTP header named
SOAPAction
with a value of
Foo
to the
my_lv
object:
my_lv.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 an argument to
addRequestHeader()
.
var headers = ["Content-Type", "text/plain", "X-ClientAppVersion", "2.0"];
my_lv.addRequestHeader(headers);
The following example creates a new LoadVars object that adds a request header called
FLASH-UUID
. The header contains a variable that can be checked by the server.
var my_lv:LoadVars = new LoadVars();
my_lv.addRequestHeader("FLASH-UUID", "41472");
my_lv.name = "Mort";
my_lv.age = 26;
my_lv.send("http://flash-mx.com/mm/cgivars.cfm", "_blank", "POST");
