refreshing web browser with perl

Is there an HTML command that I can insert into a perl script to refresh the web browser?
What I am doing is tring to put a small piece of HTML at the front end of a script that puts up a message "please wait while script loads" while my script goes through some time consuming computations. Once these computations are done, I would like to clear the contents of the browser and display a fresh set of HTML. Right now, my script simply lays the new stuff after my "loading script" message, without refreshing (or clearing) the browser.

Thank you.

use can use Java Script Tag

<scrpit>
window.refresh()
</scrpit>

I think This will help to refresh ur window
