is swf file stored in browser cache?

[Craig Ferrante]

      this maybe a stupid question but I was'nt aware of this before. If the flash swf file
is stored in cache can't anyone take your work and create a projector file with it?
One of the reasons I choose to start working with Flash is because the graphic work
seemed more protected than other animations like gif,etc.Could someone take the swf
file right from cache and use it to create screensavers and other projector type media
from your work?Is there anyway to change the properties of the swf files to avoid this?
 

Thanks in advance
