If you are accessing the swf directly, that is, without an html (or
jsp, asp, cfx) wrapper, then within your ActionScript, you can query
whether the query string is empty using:
Application.application.parameters.length == 0
If you are using a wrapper, you would first need some javascript or
server pages code to pass the query string into the swf being loaded.
For example, I use a jsp wrapper template, which is very much like the
default html template except for something like this:
AC_FL_RunContent(
"src", "${swf}?<%= request.getQueryString() %>", . . .
