Connect to the debugger in website

Hi,

I'm working on a new site which has a couple of stages before the Flash movie I want to debug runs, first you need to login to the site, then complete a coupl e of forms, then the Flash movie loads. I'd like to be able to step through the Flex code for this movie, but I can't connect by launching the login page through the Launch configurations in Flash Builder.

The source code for the site is in one directory while the Flex app source code is in another, so when I call the compiled debug version of the swf it does not load in the site.

Is there a way I can connect with the Flash Debugger and step through my code? I'm running tomcat 6 as the server if that helps.

Thanks

Stephen
