HTTP URLRequest in Adobe Flex - apache-flex

Question

Im trying to make a simple HTTP URLReqest in Adobe Flex, heres the code roughly:
var requestSender:URLLoader = new URLLoader();
var urlRequest :URLRequest = new URLRequest("http://localhost:8888");
var msg:String = "data=blah";
urlRequest.data = msg;
urlRequest.contentType = "application/x-www-form-urlencoded";
urlRequest.method = URLRequestMethod.POST;
This produces something close to:
POST / HTTP/1.1
Referer: app:/PersonSearch.swf
Accept: text/xml, application/xml, application/xhtml+xml, ...
x-flash-version: 10,1,85,3
Content-Type: application/x-www-form-urlencoded
Content-Length: 102
Accept-Encoding: gzip,deflate
User-Agent: Mozilla/5.0 (Windows; U; en-US) ...
Host: 127.0.0.1:8888
Connection: Keep-Alive
data=blah
What I really want is:
POST / HTTP/1.1
Content-Type:application/x-www-form-urlencoded
Connection:close
Via:MDS_777
Accept:*/ *
Host:localhost:8888
Content-Length:104
data=blah
Anyone know how I remove the fields like Accept-Encoding, add fields like "Via" and set Connection to "close"?
Also how do we get the responce from the HTTP request?
Thanks
Phil

The Flash Player doesn't allow you to change the Accept-Encoding or Via headers through ActionScript. If you try do that you will get a message like this one:
Error #2096: The HTTP request header
Accept-Encoding cannot be set via
ActionScript.
If you are using URL variables you can try to simplify your code by doing this:
var variables:URLVariables = new URLVariables();
variables.data = "blah"; //same as doing data=blah
variables.data2 = "blah2"; //same as doing data2=blah2
var requestSender:URLLoader = new URLLoader();
var urlRequest:URLRequest = new URLRequest("http://localhost:8888");
urlRequest.method = URLRequestMethod.POST;
urlRequest.data = variables;
To get the response you will have to listen for the Event.COMPLETE on the "requestSender":
requestSender.addEventListener(Event.COMPLETE, completeHandler);
private function completeHandler(event:Event):void {
// do something with requestSender.data (or URLLoader(event.target).data)
}
