Refreshing of page

[amitg]

Hi Guys

I am working on a browser based web application. I have say two files "file1.asp" and "file2.asp".
I open "file2.asp" from "file1.asp" by clicking on an icon or a button.
I click on an icon in "file2.asp" and close "file2.asp".
Now, what I want is that "file1.asp" should refresh itself when "file2.asp" closes. How can I do that?

Thanks

There is some modification in question.
The two files open in different windows.
