Does unloading swf from target kill cache?

Just curious… I’m working on a portfolio section which will be loaded into a main.swf… but in that movie, I also load swfs. I was curious… If I were to set code on a button that loaded a swf and then checked to see if a statement is false and would unload the swf from the target mc… would it uncache the file? I know that’s a problem with just loading movies and unloading them, but didn’t know if once it was loaded in the target if it would actually unload from the cache or not?

thanks
