How to open a webpage in a different frame of my Web Application??

Question

How to open a webpage in a different frame of my Web Application?? Hi, I am designing a website which has two frames. The LEFT frame is the main web form of my ASP.NET web application, and the RIGHT frame is used to show other pages of my site. For example, I would like to show the web page of Google in the right frame when a Button (or HyperLink, or whatever) of my application is clicked. How can I refer to the RIGHT frame of my page, instead of opening Google in the LEFT frame where my web application is being executed?? If I use Response.Redirect("http://www.google.com/");, it is opened in the LEFT frame, which is where my web application is being executed, and I would like it to open in the RIGHT one. Any ideas to solve this problem? Thanks, goraperas P.D. I know the possibility of opening the page in a new window, but I don’t need that.
