Refresh the users browser using AS2?

aloha Kirupa Community!

is there a way to refresh the users browser using actionscript 2?

my reason for this is… i am showing some sensitive material that requires an NDA from the viewer. the material is in the form of .flv movies that are embedded in my flash site. after we allow people to watch the movies i go to our servers and delete the .flv files. however some web browsers keep this in their cache, like IE. So basically i want o know if there is a script i can use that will refresh the viewers browser after we view it and after i delete the .flv files causing the .flv files to no longer be in their cache.

any help is appreciated much
