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

headerValue. 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:

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.

Availability: ActionScript 1.0; Flash Lite 2.0

Parameters

header:Object - A string or array of strings that represents an HTTP request header name.

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

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");
