Debugging Server-hosted SWF with Flash Builder Debug Tools

Over-The-Shoulder Quick Tip

You have a Debug SWF uploaded to your server and want to use Flash Builder’s debugger features on it. You need to debug it from within its server environment for whatever reason. How do you initiate a debugger session in Flash Builder that connects with the debug-enabled SWF running from your server in the browser?

Answer: in Flash Builder’s Debug Configurations panel, set the *URL or path to launch* to “about:Blank”. Launch that debug configuration. Flash Builder begins listening for a debug SWF to be launched. Now launch the html page on the web that is hosting the debug-enabled SWF (in a browser with the debug version of the Flash Player installed). Flash Builder detects the SWF and begins debugging.
