addRequestHeader (LoadVars.addRequestHeader method)
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.
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.
The following example adds a custom HTTP header named SOAPAction with a value of Foo to the my_lv object:
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");
