Newbie problem, I think, I need to POST to a php script that has underscores in the variables names. Using the code below the underscores are sent as &5F
So the result is: http://localhost/admin/index.php?sec=user&admin&5Faction=add&place&5F=2 <mx:HTTPService resultFormat="text" result="userResult(event)" id="httpAdduser" url="http://localhost/admin/index.php?sec=user" showBusyCursor="true" useProxy="false" method="POST"> <mx:request xmlns=""> <admin_action>add</admin_action> <place_next>2</place_next> </mx:request> </mx:HTTPService> I will welcome any workaround, Action Script based, mod-rewrite, tin foil and bailing wire...
