My Local Server @ its own bandwidth?

Hi ppl!
I need some help!

I’ve created a Flash Site…And I need some testing to be done!
I run IIS and can even run other servers on my machine!..

I want to test all my External Preloaders…That is the bandwidth profiler only tests the Main.swf…by pressing Ctrl+Enter twice and we can see out Main.swf Preloading…but we cant see the External swfs preloading!

Is there a server which acts like the bandwidth profiler where we can use custom settings like presets 56K, 28.8K in the Debug Mode Menu when u test your settings!

So! It will be easier than testing your files online…I mean its better to run a server on your local machine by typing http://localhost or http://127.0.0.1 reather than uploading files everytime online esp on a 56kbps modem!

Can ne one help me?
thanks!
