Can somebody please tell me how to refresh a page from another page?

Basically, I have a little javascript pop-up window that opens when the user clicks on a link to delete the contents of their shopping_cart.

This window loads up a small html page and asks the user to confirm that they wish to delete the contents of their cart.

If they choose yes, this removes the appropriate records from a database.

So that these changes are reflected on the main page, after the user confirms their desire to delete the records, I'd like this main page to be refreshed by the pop-up window.

Does anybody know if this is poss. please?
