Dynamic HTTPService URL

Question

How about when i wanted my HTTPService url to become dynamic
that it gets from an external text file or xml file. Here is an
exampl...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:remoting="com.oreilly.
programmingflex.rpc.*" layout="absolute"
initialize="initializeHandler(event)">
<mx:Script>
<![CDATA[
private function initializeHandler(event:Event):void {
textService.send( );
private function resultHandler(event:Event):void {
textArea.text = String(textService.lastResult);
]]>
</mx:Script>
<!--<mx:HTTPService id="feedRequest" url="ip.txt"
result="resultHandler(event)" useProxy="false"/>-->
<mx:HTTPService id="textService" url="
http://yourdomainname.com/ip.xml"
result="resultHandler(event)" />
<mx:TextArea id="textArea" width="500"/>
<mx:VideoDisplay id="vid"
source="{textService.lastResult.subscribers.thevideo}" width="450"
height="338" x="20" y="75" />
</mx:Application>
As you can see my HTTPService URL points to a file named
ip.txt, the file includes my database URL where i will get my files
to be played in my VideoDisplay. Is there anybody who can help me
with this stuff. any reply would be very much appreciated.
thanks!!!

Answer 1

Are you asking if you can make the URL property of the
HTTPService that points to the textService dynamic?
You can bind the property to some local variable that is
dynamically built:
<mx:HTTPService id="textService" url="{someXMLFilePath}"
result="resultHandler(event)" />
The someXMLFilePath variable can be built in the
initializeHandler ( or where ever you want).
