problem with refresh page

[crwtrue]

I have following problem: In my website i open a new page in popup window by an link. How can you refresh the page that opended the link when you close the popup window? In that popup window i do changes to the database and it would be nice if the main window would refresh when i close the popup window. So you can see instantly without refresing the brower the results of your updates.

When i searced from google i found that php function header could maybe work, so i put an form with input button to the popup window page and to the main page code that read the POST variable and if sentence to verify if user has come back from popup window page but no refresh.

So how these things are normally done? javascript?meta tag?
Is this thing impossible to do without sessions? i mean go one page and come back.
