[flexcoders] Dynamic URLs

[markcavins]

Is there a way to take the results from form data services
        
<mx:HTTPService id="login_user" result="checkLogin(event)"
showBusyCursor="true" method="POST"
url="https://cfg0013.zonarsystems.net/interface.php"; useProxy="false">
                <mx:request xmlns="">
                <customer>
                                {customer.text}
                        </customer>
                        <username>
                                {username.text}
                        </username>
                        <password>
                                {password.text}
                        </password>
                </mx:request>
        </mx:HTTPService>

and use it to dyanamically populate a url

https://{customer.text}.mysite.net/interface.php?action=showopen&amp;operation=showassets&amp;format=xml&amp;opstatus=crit&amp;username={username.text}&amp;password={password.text}

I know how to do this in most other languages but I am completely noob
when it comes to Flex/Flash action script and I'm not quite sure how
you would set this up but I only want to make this app once so that
any customer can login and get information on their own information.
