How to refresh a document of the server??

Hi, I have a Microsoft Word document on my server, which is modified by making certain actions in my ASP.NET web application, and I would like to show this document when the user clicks on a button. The problem is that the user always gets the initial version of the Word document, without any changes. If I close the application and open again the document I can see that it has been modified. Is there any way to refresh the document, so that the user doesn't have to close the application to see the changes? Thanks, goraperas P.D. I use javascript to open the document on a certain frame of my web page: string args = "top.frames['right'].location='url_of_my_document';"; Response.Write("");
