This Example involves passing parameters from Flex to ColdFusion and then having ColdFusion Process what we need and sending it back to flex via flashvars. The HTTPService class is much slower than say using the RemoteObject class or even the WebService class but If you are not doing any heavy lifting like this example then you should not be seeing any performance difference. Instead of a CFC file we use a CFM file and the parameters being passed are actually in the URL of the CFM file and not to a function. For Example when You Enter your name it will be like http://mySite.com/myFile.cfm?yourName=ColdFusion. Click Here for the Example and the Source Code is Enabled.
